Merge tag 'ksmbd-for-7.3-rc2-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/linkinjeon/smb

Pull smb server fixes from Namjae Jeon:

 - Fix a tree connection use-after-free in smb2_tree_connect() by
   balancing references across concurrent connect, disconnect, and
   session logoff paths.

 - Validate source and target ranges in COPYCHUNK requests before range
   locking and copy operations.

 - Fix an oplock break notification UAF by acquiring a connection
   reference under ksmbd_inode lock and releasing it after the
   notification work completes.

 - Fix the sparc build by using an unsigned int for the atomic work
   state, ensuring xchg() uses a supported four-byte operation.
