block: Backport of various I/O topology fixes from 2.6.33 and 2.6.34

2010-04-01T22:58:56Z

block: Backport of various I/O topology fixes from 2.6.33 and 2.6.34 The stacking code incorrectly scaled up the data offset in some cases causing misaligned devices to report alignment. Rewrite the stacking algorithm to remedy this. (Upstream commit 9504e0864b58b4a304820dcf3755f1da80d5e72f) The top device misalignment flag would not be set if the added bottom device was already misaligned as opposed to causing a stacking failure. Also massage the reporting so that an error is only returned if adding the bottom device caused the misalignment. I.e. don't return an error if the top is already flagged as misaligned. (Upstream commit fe0b393f2c0a0d23a9bc9ed7dc51a1ee511098bd) lcm() was defined to take integer-sized arguments. The supplied arguments are multiplied, however, causing us to overflow given sufficiently large input. That in turn led to incorrect optimal I/O size reporting in some cases. Switch lcm() over to unsigned long similar to gcd() and move the function from blk-settings.c to lib. Signed-off-by: Martin K. Petersen Reviewed-by: Mike Snitzer Signed-off-by: Greg Kroah-Hartman

quota: manage reserved space when quota is not active [v2]

2010-04-01T22:58:53Z

commit c469070aea5a0ada45a836937c776fd3083dae2b upstream. Since we implemented generic reserved space management interface, then it is possible to account reserved space even when quota is not active (similar to i_blocks/i_bytes). Without this patch following testcase result in massive comlain from WARN_ON in dquot_claim_space() TEST_CASE: mount /dev/sdb /mnt -oquota dd if=/dev/zero of=/mnt/test bs=1M count=1 quotaon /mnt # fs_reserved_spave == 1Mb # quota_reserved_space == 0, because quota was disabled dd if=/dev/zero of=/mnt/test seek=1 bs=1M count=1 # fs_reserved_spave == 2Mb # quota_reserved_space == 1Mb sync # ->dquot_claim_space() -> WARN_ON Signed-off-by: Dmitry Monakhov Signed-off-by: Jan Kara Signed-off-by: Greg Kroah-Hartman

mac80211: Retry null data frame for power save

2010-04-01T22:58:52Z

commit 375177bf35efc08e1bd37bbda4cc0c8cc4db8500 upstream. Even if the null data frame is not acked by the AP, mac80211 goes into power save. This might lead to loss of frames from the AP. Prevent this by restarting dynamic_ps_timer when ack is not received for null data frames. Cc: Johannes Berg Signed-off-by: Vivek Natarajan Signed-off-by: John W. Linville Signed-off-by: Luis R.

if_tunnel.h: add missing ams/byteorder.h include

2010-04-01T22:58:42Z

commit 9bf35c8dddd56f7f247a27346f74f5adc18071f4 upstream. When compiling userspace application which includes if_tunnel.h and uses GRE_* defines you will get undefined reference to __cpu_to_be16.

tty: Take a 256 byte padding into account when buffering below sub-page units

2010-04-01T22:58:31Z

commit 352fa6ad16b89f8ffd1a93b4419b1a8f2259feab upstream. The TTY layer takes some care to ensure that only sub-page allocations are made with interrupts disabled. It does this by setting a goal of "TTY_BUFFER_PAGE" to allocate. Unfortunately, while TTY_BUFFER_PAGE takes the size of tty_buffer into account, it fails to account that tty_buffer_find() rounds the buffer size out to the next 256 byte boundary before adding on the size of the tty_buffer. This patch adjusts the TTY_BUFFER_PAGE calculation to take into account the size of the tty_buffer and the padding. Once applied, tty_buffer_alloc() should not require high-order allocations.

tty: Keep the default buffering to sub-page units

2010-04-01T22:58:30Z

commit d9661adfb8e53a7647360140af3b92284cbe52d4 upstream. We allocate during interrupts so while our buffering is normally diced up small anyway on some hardware at speed we can pressure the VM excessively for page pairs. We don't really need big buffers to be linear so don't try so hard. In order to make this work well we will tidy up excess callers to request_room, which cannot itself enforce this break up.
