From: Lukas Czerner Date: Sat, 12 Apr 2014 13:47:00 +0000 (-0400) Subject: ext4: remove unnecessary check for APPEND and IMMUTABLE X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=9ef06cec7c96f6bf59f1dd8b64b9645820099051;p=openwrt%2Fstaging%2Fblogic.git 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.
