* ext2: Zero our b_size in ext2_quota_read()Manish Katiyar2009-03-261-0/+1
| | | | | | | | | | ext2_quota_read() doesn't initialize tmp_bh.b_size before calling ext2_get_block() where we access it. Since it is a local variable it might contain some garbage. Make sure it is filled with reasonable value before passing. Signed-off-by: Manish Katiyar <mkatiyar@gmail.com> Signed-off-by: Jan Kara <jack@suse.cz>

| | | | | | | | | | | | Uses quota reservation/claim/release to handle quota properly for delayed allocation in the three steps: 1) quotas are reserved when data being copied to cache when block allocation is defered 2) when new blocks are allocated. reserved quotas are converted to the real allocated quota, 2) over-booked quotas for metadata blocks are released back.

* quota: Add quota reservation supportMingming Cao2009-03-263-31/+110
| | | | | | | | | | | | | | Delayed allocation defers the block allocation at the dirty pages flush-out time, doing quota charge/check at that time is too late. But we can't charge the quota blocks until blocks are really allocated, otherwise users could get overcharged after reboot from system crash. This patch adds quota reservation for delayed allocation. Quota blocks are reserved in memory, inode and quota won't gets dirtied until later block allocation time. Signed-off-by: Mingming Cao <cmm@us.ibm.com> Signed-off-by: Jan Kara <jack@suse.cz>

| | | | | | | | | | | | | | | | | | | With a sufficiently new compiler and binutils, code which wasn't previously generating .eh_frame sections has begun to. Certain architectures (powerpc, in this case) may generate unexpected relocation formats in response to this, preventing modules from loading. While the new relocation types should probably be handled, revert to the previous behaviour with regards to generation of .eh_frame sections.

Also, since we fully construct phy_bus_id in the _probe() routine, we no longer need ->phy_address and ->mdio_bus fields in ucc_geth_info structure. I wish the patch would be a bit shorter, but it seems like the only way to fix the issue in a sane way. Luckily, the patch has been tested with real PHYs and fixed-link, so no further regressions expected.

| * dm9000: locking bugfixDavid Brownell2009-03-221-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a locking bug in the dm9000 driver. It calls request_irq() without setting IRQF_DISABLED ... which is correct for handlers that support IRQ sharing, since that behavior is not guaranteed for shared IRQs. However, its IRQ handler then wrongly assumes that IRQs are blocked. So the fix just uses the right spinlock primitives in the IRQ handler. NOTE: this is a classic example of the type of bug which lockdep currently masks by forcibly setting IRQF_DISABLED on IRQ handlers that did not request that flag.

| * smsc911x: reset last known duplex and carrier on openSteve Glendinning2009-03-181-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | smsc911x_phy_adjust_link is called periodically by the phy layer (as it's run in polling mode), and it only updates the hardware when it sees a change in duplex or carrier. This patch clears the last known values every time the interface is brought up, instead of only when the module is loaded. Without this patch the adjust_link function never updates the hardware after an ifconfig down; ifconfig up. On a full duplex link this causes the tx error counter to increment, even though packets are correctly transmitted, as the default MAC_CR register setting is for half duplex. The tx errors are "no carrier" errors, which should be ignored in full-duplex mode. When MAC_CR is set to "full duplex" mode they are correctly ignored by the hardware. Note that even with this patch the tx error counter can increment if packets are transmitted between "ifconfig up" and the first phy poll interval. An improved solution would use the phy interrupt with phylib, but I haven't managed to make this work 100% robustly yet.
