Description Jeff Layton 2010-02-08 20:04:42 UTC

+++ This bug was initially created as a clone of Bug #562788 +++

Upstream has has a rash of elusive problem reports in the last several months with CIFS. I finally was able to get a reproducer and track down the cause of at least one of them.

...I also have a patch queued up to fix the way dentries are hashed in the readdir code for case-insensitive mounts.

Comment 1 Jeff Layton 2010-02-08 20:05:51 UTC

Note that these bugs are generally papered over on RHEL5 by the fact that "noserverino" is the default there.

Comment 2 Jeff Layton 2010-02-12 14:21:50 UTC

Setting blocker flag and changing this to a more generic title.

Comment 4 Jeff Layton 2010-02-12 14:37:46 UTC

I'd like to see these patches make 5.5. They just hit mainline a day or two ago, but are small fixes and probably ought to go in.

    BZ#562947: CIFS shouldn't make mountpoints shrinkable
