| | | | | | | | | unlock was resulting in leak of lock structure if it was unlocking the last existing lock Signed-off-by: Anand V. Avati <avati@dev.gluster.com> BUG: 306 (Enhance locks to aid debugging) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=306
* storage/posix: Set right the op_ret value from posix_readlink()Vijay Bellur2009-10-181-4/+6
| | | | | | | | | | Since op_ret was being returned as 0, fuse would regard the readlink () as a failure. Also, set right the buffer size of gen_key in posix_{f, l}stat_with_gen.
