am-utils-6.2 - fix Linux NFS recognition of umounts
|
||
|
|
|
||
|
|
From: Ian Kent <raven@themaw.net>
|
||
|
|
|
||
|
|
Recent Linux NFS uses a simulated attibute cache change detection
|
||
|
|
method based on ctime. Consequenty the amd use of mtime for this
|
||
|
|
doesn't work properly for some kernel versions.
|
||
|
|
|
||
|
|
The problem seen with some kernel versions is a failure to recognize
|
||
|
|
umounts.
|
||
|
|
|
||
|
|
Updating the parent ctime in step with mtime during umount appears
|
||
|
|
to fix the problem.
