| H A D | dm-snap.c | e50f8306 Wed Mar 20 12:43:11 CDT 2024 Mikulas Patocka <mpatocka@redhat.com> dm snapshot: fix lockup in dm_exception_table_exit
[ Upstream commit 6e7132ed3c07bd8a6ce3db4bb307ef2852b322dc ]
There was reported lockup when we exit a snapshot with many exceptions.
Fix this by adding "cond_resched" to the loop that frees the exceptions.
