[PATCH] ACPI: EC: limit multibyte access to EC to 8 byte
commit dadf28a10c3eb29421837a2e413ab869ebd9e168 enabled multibyte access to EC, but ignored that the consuming function expects the bitfields to be in chunks of maximal 64 bit. So limit multibyte access to 8 byte to prevent error in the ACPI layer. Signed-off-by: Alexander Rauth <alexander.rauth(a)promotion-ie.de> ... 16 Apr 2010 12:51

[PATCH] fs-writeback : check sync bit earlier in inode_wait_for_writeback
When wb_writeback() hasn't written anything it will re-acquire the inode lock before calling inode_wait_for_writeback. This change tests the sync bit first so that is doesn't need to drop & re-acquire the lock if the inode became available while wb_writeback() was waiting to get the lock.
