Subject: ext3: update ctime when changing the file's permission by setfacl
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=30e2bab2d6e22188c6d36a09cdcffb4748d2dbe5;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ext3: update ctime when changing the file's permission by setfacl

ext3 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, ext3 must update it.
