Subject: jfs: compare old and new mode before setting update_mode flag
X-Git-Tag: v5.2-rc1~162^2~2

jfs: compare old and new mode before setting update_mode flag

If new mode is the same as old mode we don't have to reset
inode mode in the rest of the code, so compare old and new
mode before setting update_mode flag.
