Subject: [PATCH 423/449] ctime: Fix ctime inconsisteny with utimensat
|
|
|
|
Problem:
|
|
When touch is used to create a file, the ctime is not matching
|
|
atime and mtime which ideally should match. There is a difference
|
|
in nano seconds.
|
|
|
|
Cause:
|
|
When touch is used modify atime or mtime to current time (UTIME_NOW),
|
|
the current time is taken from kernel. The ctime gets updated to current
|
|
time when atime or mtime is updated. But the current time to update
|
|
ctime is taken from utime xlator. Hence the difference in nano seconds.
|
|
|
|
Fix:
|
|
When utimesat uses UTIME_NOW, use the current time from kernel.
