3.5.7u1 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Sage Weil <s...@inktank.com>
commit 89a86be0ce20022f6ede8bccec078dbb3d63caaa upstream.
Once we call ->connect(), we are racing against the actual
connection, and a subsequent transition from CONNECTING ->
CONNECTED. Set the state to CONNECTING before that, under the
protection of the mutex, to avoid the race.
This was introduced in 928443cd9644e7cfd46f687dbeffda2d1a357ff9,
with the original socket state code.
