[RFC PATCH 00/11] smb/server: change notify support

From: ChenXiaoSong <[email protected]>

Sorry for taking such a long time to complete the ksmbd change notify feature.
Over the past few months, I have been busy with the birth of my daughter and
my PhD-related tasks, which left me with limited time to work on it.

Once Gaël updates his patch ("ksmbd: defer CHANGE_NOTIFY completion instead of STATUS_NOT_IMPLEMENTED"),
I will rebase my patchset on top of it.

To test this feature, the following patches need to be applied to cifs-utils and kernel smb client:
  - cifs-utils: https://chenxiaosong.com/lkml/cifs-utils-parse-notify
  - kernel smb client: https://chenxiaosong.com/lkml/cifs-improve-notify

The complete kernel client and server patches are also available at the following link:

ChenXiaoSong (11):
  smb/server: add debug type for change notify
  smb/server: validate notify requests
  smb/server: support canceling notify requests
  smb/server: watch directories for changes
  smb/server: keep notify watches on file handles
  smb/server: save simple notify events
  smb/server: save old names for rename notify events
  smb/server: match rename notify events
  smb/server: encode notify events
  smb/server: send notify events to the client
  smb/server: break directory leases before sending notify events
