Subject: ext4: don't set i_flags in EXT4_IOC_SETFLAGS
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3.5.0-rc1-00002-gb22b1f1;p=linux-beck.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.
