Thank you. This unlock/lock pair exists only in FreeBSD version of drm. It was introdu= ced in 4.12 by johalun@ to workaround unknown bug, probably taking sleepable lo= ck with non-slepable lock held and effectively reverted in 4.19 with comment "Fixes amdgpu". I'll try to test it on i915 after getting some spare time to ensure that the "unknown bug" does not resurrect. --=20 You are receiving this mail because: You are on the CC list for the bug.=
