Subject: ext4: don't set i_flags in EXT4_IOC_SETFLAGS
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b22b1f178f6799278d3178d894f37facb2085765;p=openwrt%2Fstaging%2Fblogic.git

ext4: don't set i_flags in EXT4_IOC_SETFLAGS

Commit 7990696 uses the ext4_{set,clear}_inode_flags() functions to
change the i_flags automatically but fails to remove the error setting
of i_flags.  So we still have the problem of trashing state flags.
Fix this by removing the assignment.
