Description Flags
Patch - autofs4 - fix reset pending flag on mount fail none

Description Ian Kent 2012-10-15 00:53:48 UTC 
Description of problem:
When using the browse option a mount fail when accessing an
automounted directory results in the attributes of the directory
(owner, group, mode, access time) are being listed as unknown.

Version-Release number of selected component (if applicable):
All kernel versions.

How reproducible:
Always with the steps below.

Steps to Reproduce:

Make sure you have BROWSE_MODE="yes" in /etc/sysconfig/autofs.

1. Add a simple indirect mount map (it's required that
   the server does NOT export the /notexported directory):

# cat /etc/auto.master
/nfs    /etc/auto.nfs

# cat /etc/auto.nfs
v2      server:/notexported

2. Restart AutoFS and try to access the directory:

# cd /nfs/v2
-bash: cd: /nfs/v2: No such file or directory

3. List the contents of the indirect mount directory.

# ls -la /nfs
ls: cannot access /nfs/v2: No such file or directory
total 4
drwxr-xr-x  3 root root    0 Sep 24 21:43 .
drwxr-xr-x 28 root root 4096 Sep 24 21:25 ..
d?????????  ? ?    ?       ?            ? v2


Actual results:
As above in step 3.

Expected results:
Sensible attributes, in this case attributes of the directory
as they should be in the autofs file system.
