* jbd2: Annotate transaction start also for jbd2_journal_restart()Jan Kara2009-08-171-2/+3
| | | | | | | | | | lockdep annotation for a transaction start has been at the end of jbd2_journal_start(). But a transaction is also started from jbd2_journal_restart().

* ext4: Avoid group preallocation for closed filesTheodore Ts'o2009-09-182-2/+38
| | | | | | | | | | | | | | | | | | | | | | Currently the group preallocation code tries to find a large (512) free block from which to do per-cpu group allocation for small files. The problem with this scheme is that it leaves the filesystem horribly fragmented. In the worst case, if the filesystem is unmounted and remounted (after a system shutdown, for example) we forget the fact that wee were using a particular (now-partially filled) 512 block extent. So the next time we try to allocate space for a small file, we will find *another* completely free 512 block chunk to allocate small files. Given that there are 32,768 blocks in a block group, after 64 iterations of "mount, write one 4k file in a directory, unmount", the block group will have 64 files, each separated by 511 blocks, and the block group will no longer have any free 512 completely free chunks of blocks for group preallocation space. So if we try to allocate blocks for a file that has been closed, such that we know the final size of the file, and the filesystem is not busy, avoid using group preallocation.

* ext4: Fix bugs in mballoc's stream allocation modeTheodore Ts'o2009-08-092-13/+12
| | | | | | | | | | | | | | | | The logic around sbi->s_mb_last_group and sbi->s_mb_last_start was all screwed up. These fields were getting unconditionally all the time, set even when stream allocation had not taken place, and if they were being used when the file was smaller than s_mb_stream_request, which is when the allocation should _not_ be doing stream allocation. Fix this by determining whether or not we stream allocation should take place once, in ext4_mb_group_or_file(), and setting a flag which gets used in ext4_mb_regular_allocator() and ext4_mb_use_best_found(). This simplifies the code and assures that we are consistently using (or not using) the stream allocation logic. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

* ext4: fix journal ref count in move_extent_par_pagePeng Tao2009-08-101-0/+1
| | | | | | | | | | | | move_extent_par_page calls a_ops->write_begin() to increase journal handler's reference count. However, if either mext_replace_branches() or ext4_get_block fails, the increased reference count isn't decreased. This will cause a later attempt to umount of the fs to hang forever. The patch addresses the issue by calling ext4_journal_stop() if page is not NULL (which means a_ops->write_end() isn't invoked).

* ext4: More buffer head reference leaksCurt Wohlgemuth2009-07-172-5/+14
| | | | | | | | | | | | | | | | | | | | | | After the patch I posted last week regarding buffer head ref leaks in no-journal mode, I looked at all the code that uses buffer heads and searched for more potential leaks. The patch below fixes the issues I found; these can occur even when a journal is present. The change to inode.c fixes a double release if ext4_journal_get_create_access() fails. The changes to namei.c are more complicated. add_dirent_to_buf() will release the input buffer head EXCEPT when it returns -ENOSPC. There are some callers of this routine that don't always do the brelse() in the event that -ENOSPC is returned. Unfortunately, to put this fix into ext4_add_entry() required capturing the return value of make_indexed_dir() and add_dirent_to_buf().

* ext4: Fix memory leak fix when mounting an ext4 filesystemAneesh Kumar K.V2009-07-171-19/+0
| | | | | | | | | | | | | | | | | The allocation of the ext4_group_info array was moved to a new function ext4_mb_add_group_info() in commit 5f21b0e6 so that online resize would use a common (and correct) codepath. Unfortunately, the call to the new ext4_mb_add_group_info() function was added without removing the code which originally allocated the array. This caused a memory leak each time an ext4 filesystem was mounted. The fix is simple; remove the code that did the original allocation, since it is no longer needed.

Every device with a major/minor will provide a device node in devtmpfs. Devtmpfs can be changed and altered by userspace at any time, and in any way needed - just like today's udev-mounted tmpfs. Unmodified udev versions will run just fine on top of it, and will recognize an already existing kernel-created device node and use it. The default node permissions are root:root 0600. Proper permissions and user/group ownership, meaningful symlinks, all other policy still needs to be applied by userspace. If a node is created by devtmps, devtmpfs will remove the device node when the device goes away. If the device node was created by userspace, or the devtmpfs created node was replaced by userspace, it will no longer be removed by devtmpfs. If it is requested to auto-mount it, it makes init=/bin/sh work without any further userspace support. /dev will be fully populated and dynamic, and always reflect the current device state of the kernel. With the commonly used dynamic device numbers, it solves the problem where static devices nodes may point to the wrong devices. It is intended to make the initial bootup logic simpler and more robust, by de-coupling the creation of the inital environment, to reliably run userspace processes, from a complex userspace bootstrap logic to provide a working /dev.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When turning class devices into bus devices, we may need to temporarily add links in sysfs so that user-space applications are not confused. This is done by adding the following API: * Functions to register and unregister compatibility classes. These appear in sysfs at the same location as regular classes, but instead of class devices, they contain links to bus devices. * Functions to create and delete such links. Additionally, the caller can optionally pass a target device to which a "device" link should point (typically that would be the device's parent), to fully emulate the original class device. The i2c subsystem will be the first user of this API, as i2c adapters are being converted from class devices to bus devices.

| * uio: add generic driver for PCI 2.3 devicesMichael S. Tsirkin2009-09-156-0/+389
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a generic uio driver that can bind to any PCI device. First user will be virtualization where a qemu userspace process needs to give guest OS access to the device. Interrupts are handled using the Interrupt Disable bit in the PCI command register and Interrupt Status bit in the PCI status register. All devices compliant to PCI 2.3 (circa 2002) and all compliant PCI Express devices should support these bits. Driver detects this support, and won't bind to devices which do not support the Interrupt Disable Bit in the command register. It's expected that more features of interest to virtualization will be added to this driver in the future.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1271) affects when new devices get linked into their bus's list of devices. Currently this happens after probing, and it doesn't happen at all if probing fails. Clearly this is wrong, because at that point quite a few symbolic links have already been created in sysfs. We are committed to adding the device, so it should be linked into the bus's list regardless. In addition, this needs to happen before the uevent announcing the new device gets issued. Otherwise user programs might try to access the device before it has been added to the bus. To fix both these problems, the patch moves the call to klist_add_tail() forward from bus_attach_device() to bus_add_device(). Since bus_attach_device() now does nothing but probe for drivers, it has been renamed to bus_probe_device(). And lastly, the kerneldoc is updated.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is already an in-kernel driver for this hardware (since 2.6.30), at76c50x-usb, and it supports all of the same devices. So this driver can now be deleted. Acked-by: Kalle Valo <kalle.valo@iki.fi> Cc: linux-wireless <linux-wireless@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
