Red Hat Bugzilla – Bug 562949
problems with aliased dentries and case-insensitivity in CIFS readdir code
Last modified: 2013-03-03 19:20:31 EST
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. http://git.kernel.org/?p=linux/kernel/git/sfrench/cifs-2.6.git;a=commitdiff;h=f12f98dba6ea1517cd7fbb912208893b9c014c15 ...I also have a patch queued up to fix the way dentries are hashed in the readdir code for case-insensitive mounts. Note that these bugs are generally papered over on RHEL4 by the fact that "noserverino" is the default there.
