Revision e0339f036ef4beb9b20f0b6532a1e0ece7f594c6 authored by David Howells on 28 July 2022, 09:31:06 UTC, committed by Linus Torvalds on 28 July 2022, 17:06:49 UTC
Since __post_watch_notification() walks wlist->watchers with only the
RCU read lock held, we need to use RCU methods to add to the list (we
already use RCU methods to remove from the list).
Fix add_watch_to_object() to use hlist_add_head_rcu() instead of
hlist_add_head() for that list.
Fixes: c73be61cede5 ("pipe: Add general notification queue support")
