Revision f52afc93cd018fe6910133a05d44671192d1aeb0 authored by Jan Kara on 27 September 2018, 11:23:32 UTC, committed by Dan Williams on 27 September 2018, 17:56:15 UTC
When dax_lock_mapping_entry() has to sleep to obtain entry lock, it will
fail to unlock mapping->i_pages spinlock and thus immediately deadlock
against itself when retrying to grab the entry lock again. Fix the
problem by unlocking mapping->i_pages before retrying.
