Subject: [PATCH 276/276] features/utime: always update ctime at setattr
|
|
|
f338ef |
|
|
|
f338ef |
For the nfs EXCLUSIVE mode create may sets a later time
|
|
|
f338ef |
to mtime (at verifier), it should not set to ctime for
|
|
|
f338ef |
storage.ctime does not allowed set ctime to a earlier time.
|
|
|
f338ef |
|
|
|
f338ef |
/* Earlier, mdata was updated only if the existing time is less
|
|
|
f338ef |
* than the time to be updated. This would fail the scenarios
|
|
|
f338ef |
* where mtime can be set to any time using the syscall. Hence
|
|
|
f338ef |
* just updating without comparison. But the ctime is not
|
|
|
f338ef |
* allowed to changed to older date.
|
|
|
f338ef |
*/
|
|
|
f338ef |
|
|
|
f338ef |
According to kernel's setattr, always set ctime at setattr,
|
|
|
f338ef |
and doesnot set ctime from mtime at storage.ctime.
