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: https://chenxiaosong.com/repo/linux/ksmbd-change-notify 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 fs/smb/server/Kconfig | 1 + fs/smb/server/Makefile | 2 +- fs/smb/server/glob.h | 3 +- fs/smb/server/notify.c | 1011 +++++++++++++++++++++++++++++++++++++ fs/smb/server/notify.h | 24 + fs/smb/server/oplock.c | 40 ++ fs/smb/server/oplock.h | 1 + fs/smb/server/server.c | 2 +- fs/smb/server/smb2pdu.c | 12 +- fs/smb/server/vfs_cache.c | 3 + fs/smb/server/vfs_cache.h | 4 + 11 files changed, 1095 insertions(+), 8 deletions(-) create mode 100644 fs/smb/server/notify.c create mode 100644 fs/smb/server/notify.h -- 2.54.0
