ksmbd: fix r_count dec/increment mismatch

Browse source

[ Upstream commit ddb7ea36ba ]

r_count is only increased when there is an oplock break wait,
so r_count inc/decrement are not paired. This can cause r_count
to become negative, which can lead to a problem where the ksmbd
thread does not terminate.

Fixes: 3aa660c059 ("ksmbd: prevent connection release during oplock break notification")
