Description
In the Linux kernel, the following vulnerability has been resolved:
af_unix: Fix a data-race in unix_dgram_peer_wake_me().
unix_dgram_poll() calls unix_dgram_peer_wake_me() without `other`'s
lock held and check if its receive queue is full. Here we need to
use unix_recvq_full_lockless() instead of unix_recvq_full(), otherwise
KCSAN will report a data-race.
