Date: Tue, 15 Apr 2014 18:41:14 +0200 From: Lukas Czerner <lczerner@...hat.com> To: linux-fsdevel@...r.kernel.org Cc: linux-ext4@...r.kernel.org, xfs@....sgi.com, Lukas Czerner <lczerner@...hat.com> Subject: [PATCH 1/3 v2] ext4: Remove unnecessary check for APPEND and IMMUTABLE All the checks IS_APPEND and IS_IMMUTABLE for the fallocate operation on the inode are done in vfs. No need to do this again in ext4. Remove it.
