* [PATCH] reiserfs: reiserfs hang and performance fix for data=journal modeChris Mason2006-02-012-5/+21
| | | | | | | | | | | | | | In data=journal mode, reiserfs writepage needs to make sure not to trigger transactions while being run under PF_MEMALLOC. This patch makes sure to redirty the page instead of forcing a transaction start in this case. Also, calling filemap_fdata* in order to trigger io on the block device can cause lock inversions on the page lock. Instead, do simple batching from flush_commit_list.

* [PATCH] resierfs: fix reiserfs_invalidatepage race against data=orderedChris Mason2006-02-012-1/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | After a transaction has closed but before it has finished commit, there is a window where data=ordered mode requires invalidatepage to pin pages instead of freeing them. This patch fixes a race between the invalidatepage checks and data=ordered writeback, and it also adds a check to the reiserfs write_ordered_buffers routines to write any anonymous buffers that were dirtied after its first writeback loop. That bug works like this: proc1: transaction closes and a new one starts proc1: write_ordered_buffers starts processing data=ordered list proc1: buffer A is cleaned and written proc2: buffer A is dirtied by another process proc2: File is truncated to zero, page A goes through invalidatepage proc2: reiserfs_invalidatepage sees dirty buffer A with reiserfs journal head, pins it proc1: write_ordered_buffers frees the journal head on buffer A At this point, buffer A stays dirty forever Signed-off-by: Chris Mason <mason@suse.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] Direct Migration V9: Avoid writeback / page_migrate() methodChristoph Lameter2006-02-015-0/+66
| | | | | | | | | | | | | | | | | | | Migrate a page with buffers without requiring writeback This introduces a new address space operation migratepage() that may be used by a filesystem to implement its own version of page migration. A version is provided that migrates buffers attached to pages. Some filesystems (ext2, ext3, xfs) are modified to utilize this feature. The swapper address space operation are modified so that a regular migrate_page() will occur for anonymous pages without writeback (migrate_pages forces every anonymous page to have a swap entry).

* [PATCH] mm: hugepage accounting fixHugh Dickins2006-02-011-2/+2
| | | | | | | | | | | | | | | | 2.6.15's hugepage faulting introduced huge_pages_needed accounting into hugetlbfs: to count how many pages are already in cache, for spot check on how far a new mapping may be allowed to extend the file. But it's muddled: each hugepage found covers HPAGE_SIZE, not PAGE_SIZE. Once pages were already in cache, it would overshoot, wrap its hugepages count backwards, and so fail a harmless repeat mapping with -ENOMEM. Fixes the problem found by Don Dupuis.

* [PATCH] fuse: fix async read for legacy filesystemsMiklos Szeredi2006-02-013-4/+22
| | | | | | | | | | | | | | | | | | | | | | | While asynchronous reads mean a performance improvement in most cases, if the filesystem assumed that reads are synchronous, then async reads may degrade performance (filesystem may receive reads out of order, which can confuse it's own readahead logic). With sshfs a 1.5 to 4 times slowdown can be measured. There's also a need for userspace filesystems to know whether asynchronous reads are supported by the kernel or not. To achive these, negotiate in the INIT request whether async reads will be used and the maximum readahead value. Update interface version to 7.6 If userspace uses a version earlier than 7.6, then disable async reads, and set maximum readahead value to the maximum read size, as done in previous versions.

This is most easily seen with an X application that uses sub-second select/poll timeout such as emacs. You hit a key and it takes a second or so before the app responds. The two ROUND_UP() calls upon entry are using {tv,ts}_sec where it should instead be using {tv_usec,ts_nsec}, which perfectly explains the observed incorrect behavior.

These system calls have to change the signal mask during their operation, and signal handlers must be invoked using the new, temporary signal mask. The old signal mask must be restored either upon successful exit from the system call, or upon returning from the invoked signal handler if the system call is interrupted. We can't simply restore the original signal mask and return to userspace, since the restored signal mask may actually block the signal which interrupted the system call. The TIF_RESTORE_SIGMASK flag deals with this by causing the syscall exit path to trap into do_signal() just as TIF_SIGPENDING does, and by causing do_signal() to use the saved signal mask instead of the current signal mask when setting up the stack frame for the signal handler -- or by causing do_signal() to simply restore the saved signal mask in the case where there is no handler to be invoked. The first patch implements the sys_pselect() and sys_ppoll() system calls, which are present only if TIF_RESTORE_SIGMASK is defined. That #ifdef should go away in time when all architectures have implemented it. The second patch implements TIF_RESTORE_SIGMASK for the PowerPC kernel (in the -mm tree), and the third patch then removes the arch-specific implementations of sys_rt_sigsuspend() and replaces them with generic versions using the same trick. The fourth and fifth patches, provided by David Howells, implement TIF_RESTORE_SIGMASK for FR-V and i386 respectively, and the sixth patch adds the syscalls to the i386 syscall table. This patch: Add the pselect() and ppoll() system calls, providing core routines usable by the original select() and poll() system calls and also the new calls (with their semantics w.r.t timeouts).

These functions, openat etc, have been discussed on numerous occasions. They are needed to implement race-free filesystem traversal, they are necessary to implement a virtual per-thread current working directory (think multi-threaded backup software), etc. We have in glibc today implementations of the interfaces which use the /proc/self/fd magic. But this code is rather expensive. Here are some results (similar to what Jim Meyering posted before). The test creates a deep directory hierarchy on a tmpfs filesystem. Then rm -fr is used to remove all directories. Without syscall support I get this: real 0m31.921s user 0m0.688s sys 0m31.234s With syscall support the results are much better: real 0m20.699s user 0m0.536s sys 0m20.149s The interfaces are for obvious reasons currently not much used. But they'll be used. coreutils (and Jeff's posixutils) are already using them. Furthermore, code like ftw/fts in libc (maybe even glob) will also start using them. I expect a patch to make follow soon. Every program which is walking the filesystem tree will benefit.

* | | | | | | [PATCH] knfsd: Provide missing NFSv2 part of patch for checking vfs_getattr.David Shaw2006-01-181-7/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A recent patch which checked the return status of vfs_getattr in nfsd, completely missed the nfsproc.c (NFSv2) part. Here is it. This patch moved the call to vfs_getattr from the xdr encoding (at which point it is too late to return an error) to the call handling. This means several calls to vfs_getattr are needed in nfsproc.c. Many are encapsulated in nfsd_return_attrs and nfsd_return_dirop.

Also, nfsd_setattr returns an nfserr which SHOULDN'T be converted from an errno (because it isn't one). Also some tidyups of the form: err = XX err = nfserrno(err) and err = XX if (err) err = nfserrno(err) become err = nfserrno(XX) Signed-off-by: Neil Brown <neilb@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* | | | | | | [PATCH] nfsd4_lock() returns bogus values to clientsAl Viro2006-01-181-0/+3

BTW, that case is not impossible - posix_lock_file() can return -ENOLCK and we do not handle that one explicitly.
