Description Sachin Prabhu 2009-04-21 15:29:28 UTC 
Patch to fix problem in bz 479432 results in a regression. The original problem reported where a large number of acl requests results in the client crashing was fixed. However normal setfacl requests which were working before now return with -EINVAL.
