| H A D | sess.c | 2b1f28ee Thu Feb 01 05:15:28 CST 2024 Shyam Prasad N <sprasad@microsoft.com> cifs: do not search for channel if server is terminating
[ Upstream commit 88675b22d34e6e815ad4bde09c590ccb2d50c59d ]
In order to scale down the channels, the following sequence
of operations happen:
1. server struct is marked for terminate
2. the channel is deallocated in the ses->chans array
3. at a later point the cifsd thread actually terminates the server
Between 2 and 3, there can be calls to find the channel for
a server struct. When that happens, there can be an ugly warning
that's logged. But this is expected.
So this change does two things:
1. in cifs_ses_get_chan_index, if server->terminate is set, return
2. always make sure server->terminate is set with chan_lock held
