cifs: avoid race conditions with parallel reconnects

Browse source

[ Upstream commit bc962159e8 ]

When multiple processes/channels do reconnects in parallel
we used to return success immediately
negotiate/session-setup/tree-connect, causing race conditions
between processes that enter the function in parallel.
This caused several errors related to session not found to
show up during parallel reconnects.
