David Sterba 7e75bf3ff3 btrfs: properly access unaligned checksum buffer ... On Fri, Mar 18, 2011 at 11:56:53AM -0400, Chris Mason wrote: > Thanks for fielding this one.

(quicktest: assembly output is same for put_unaligned_le32 and direct assignment on my x86_64) I was originally following examples in Documentation/unaligned-memory-access.txt. From other code it seems to me that the define CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS is intended for larger portions of code. Macros/wrappers for {put,get}_unaligned* are chosen via arch/<arch>/include/asm/unaligned.h accordingly, therefore it's safe to use put_unaligned_le32 without the ifdef. dave Signed-off-by: Chris Mason <chris.mason@oracle.com>		2011-03-28 05:37:36 -04:00
