Subject: jffs2: update ctime when changing the file's permission by setfacl
X-Git-Tag: v2.6.35-rc3~29^2
X-Git-Url: http://bbs.cooldavid.org/git/?a=commitdiff_plain;h=1c24d06f8e065023ebb428db5af5514500839ee6;p=net-next-2.6.git

jffs2: update ctime when changing the file's permission by setfacl

jffs2 didn't update the ctime of the file when its permission was changed.

Steps to reproduce:
 # touch aaa
 # stat -c %Z aaa
 1275289822
 # setfacl -m  'u::x,g::x,o::x' aaa
 # stat -c %Z aaa
 1275289822                         <- unchanged

But, according to the spec of the ctime, jffs2 must update it.

Port of ext3 patch by Miao Xie <miaox@cn.fujitsu.com>.
