9a0212800c s3: smbd: Add "enum brl_flavour" to struct smbd_lock_element.
Initialized correctly but not yet used.
Will allow 'brl_flavour' to be removed from lock calls.
This will allow SMB2 POSIX handles to call with POSIX_LOCK
flavour instead of always using WINDOWS_LOCK (as now).

66d92f37c3 s3:locking: add brl_req_guid() and brl_req_mem_ctx() helper functions
This allows the vfs backend to detect a retry and keep state between
the retries.

adf4833792 This patch looks bigger than it is. It does 2 things. 1). Renames smbpid -> smblctx in our locking code. 2). Widens smblctx to 64-bits internally. Preparing to use the SMB2 handle as the locking context.

f4092ecec7 Plumb the SMB2 front end into the blocking lock backend.
Metze, you'll probably be happier with this work as it
doesn't abuse tevent in the way you dislike. This is a
first cut at the code, which will need lots of testing
but I'm hoping this will give people an idea of where I'm
going with this.

e4675ce8db s3: Add extid to the dev/inode pair
This extends the file_id struct to add an additional generic uint64_t
field: extid.  For backwards compatibility with dev/inodes stored in
xattr_tdbs and acl_tdbs, the ext id is ignored for these databases.
This patch should cause no functional change on systems that don't use
SMB_VFS_FILE_ID_CREATE to set the extid.

Existing code that uses the smb_share_mode library will need to be
updated to be compatibile with the new extid.

813273c87e Add VFS ops for Windows BRL: Lock, Unlock and Cancel:
This patch adds 3 new VFS OPs for Windows byte range locking: BRL_LOCK_WINDOWS,
BRL_UNLOCK_WINDOWS and BRL_CANCEL_WINDOWS. Specifically:

* I renamed brl_lock_windows, brl_unlock_windows and brl_lock_cancel to
  *_default as the default implementations of the VFS ops.
* The blocking_lock_record (BLR) is now passed into the brl_lock_windows and
  brl_cancel_windows paths. The Onefs implementation uses it - future
  implementations may find it useful too.
* Created brl_lock_cancel to do what brl_lock/brl_unlock do: set up a
  lock_struct and call either the Posix or Windows lock function. These happen
  to be the same for the default implementation.
* Added helper functions: increment_current_lock_count() and
  decrement_current_lock_count().
* Minor spelling correction in brl_timeout_fn: brl -> blr.
* Changed blocking_lock_cancel() to return the BLR that it has cancelled. This
  allows us to assert its the lock that we wanted to cancel. If this assert ever
  fires, this path will need to take in the BLR to cancel, rather than choosing
  on its own.
* Adds a small helper function: find_blocking_lock_record_by_id(). Used by the
  OneFS implementation, but could be useful for others.

30191d1a57 RIP BOOL. Convert BOOL -> bool. I found a few interesting

BOOL == int). I also need to fix the Samba4 pidl generation

e8156439f2 r23183: Check in a change made by Tridge:
This replaces the internal explicit dev/ino file id representation by a
"struct file_id". This is necessary as cluster file systems and NFS
don't necessarily assign the same device number to the shared file
system. With this structure in place we can now easily add different
schemes to map a file to a unique 64-bit device node.

Jeremy, you might note that I did not change the external interface of
smb_share_modes.c.
