[PATCH v2 0/7] Implement byte-range locks support for SMB2

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This version has the following changes since v1:
1) sec type patch was deleted and sent separately.
2) the longterm bug, that allows one process read/write to the file region locked by another process when they use the same file handle, was fixed by checking a read/write area for a lock before an operation.

This patchset enable brlock support for SMB2 mounts. It allows brlocks
to be cached and send in portions (on oplock break or unlock range).

git branch:
http://git.altlinux.org/people/piastry/public/?p=cifs-2.6.git;a=shortlog;h=refs/heads/smb2-brlocks

Pavel Shilovsky (7):
  CIFS: Remove spinlock dependence in brlock processing
  CIFS: Move brlock code to ops struct
  CIFS: Handle SMB2 lock flags
  CIFS: Add brlock support for SMB2
  CIFS: Use brlock cache for SMB2
  CIFS: Turn lock mutex into rw semaphore
  CIFS: Check for mandatory brlocks on read/write
