  [CIFS] report rename failure when target file is locked by Windows
  [CIFS] Allow null user connections
  [CIFS] Fix readdir breakage when blocksize set too small
parents 895663cd 8e87d4dc
Version 1.46
------------
Support deep tree mounts. Better support OS/2, Win9x (DOS) time stamps.
Allow null user to be specified on mount ("username="). Do not return
EINVAL on readdir when filldir fails due to overwritten blocksize
(fixes FC problem). Return error in rename 2nd attempt retry (ie report
if rename by handle also fails, after rename by path fails, we were
not reporting whether the retry worked or not).
Version 1.45
------------
