Description of problem:
When statfs()system call is made on an automounted nfs filesystem
the call resets the automount timeout for that filesystem.
This would be a problem if a process does a periodic, say every
5 minutes( automount default timeout is 5 minutes), then the
filesystems will never be unmounted automatically.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. configure a filesystem to be nfs automounted from another m/c.
(let the automount timeout be default..(ie 5 mins)
2. cd to /net/<automunted directory>(This would mount the nfs filesystem).
3. cd elsewhere.. say cd to /
4. Run bdf ,automounted filesystem> after 2 minutes.
on the filesystem.
(wait for another 5 - 2 mins = 3 minutes)
5. verify if the filesystem is unmounted after 3 mins.
6. Verify if the filesystem is unmounted after 5 mins.
Actual Results: The filesystem did not get unmounted after 3 mins (ie 5 mins
after the filesystem was mounted) but did get unmounted after 5 minutes
(actually 7 minutes from the time the filesystem was mounted).
Expected Results: The filesystem should get unmounted automatically after 3
minutes(5 minutes from the time the filesystem was automounted).
Thanks for the bug report. However, Red Hat no longer maintains this version of
