Doc Type: Bug Fix
Doc Text:
When checking a directory tree, the kernel module could, in some circumstances, incorrectly decide the tree was not busy. An active offset mount with an open file handle being used for expires caused the file handle to not count toward the busyness check. This resulted in mount requests being made for already mounted offsets. With this update, the kernel module check has been corrected and incorrect mount requests are no longer generated.

Comment 1 Ian Kent 2008-12-09 22:23:48 EST
This fix is part of the autofs4 bug fix update for RHEL-5.3
and so needs to be applied to RHEL-4 also.

When checking a directory tree the kernel module can incorrectly decide that the tree isn't busy. This happens for the case of an active offset mount as we follow past the active offset mount, which has an open file handle which is used for expires, causing the file handle not to count toward the busyness check. This results in a mount request for an already mounted offset. The check in the kernel module has now been corrected and incorrect mount requests are not generated.
