From f689c72d7dbc7bab1cc20440ceccf2c240530d5b Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Fri, 2 Mar 2018 10:31:25 +1100 Subject: [PATCH] staging: lustre: statahead: remove incorrect test on agl_list_empty() Including agl_list_empty() in the wait_event_idle() condition is pointless as the body of the loop doesn't do anything about the agl list. So if the list wasn't empty, the while loop would spin indefinitely. The test was removed in the lustre-release commit 672ab0e00d61 ("LU-3270 statahead: small fixes and cleanup"), but not in the Linux commit 5231f7651c55 ("staging: lustre: statahead: small fixes and cleanup").
