From: Matthew Brost Date: Thu, 9 Sep 2021 16:47:28 +0000 (-0700) Subject: Revert "drm/i915/gt: Propagate change in error status to children on unhold" X-Git-Url: https://git.baikalelectronics.ru/sdk/?a=commitdiff_plain;h=ac653dd7996edf1770959e11a078312928bd7315;p=kernel.git Revert "drm/i915/gt: Propagate change in error status to children on unhold" Propagating errors to dependent fences is broken and can lead to errors from one client ending up in another. In commit 3761baae908a ("Revert "drm/i915: Propagate errors on awaiting already signaled fences""), we attempted to get rid of fence error propagation but missed the case added in commit 8e9f84cf5cac ("drm/i915/gt: Propagate change in error status to children on unhold"). Revert that one too. This error was found by an up-and-coming selftest which triggers a reset during request cancellation and verifies that subsequent requests complete successfully. v2: (Daniel Vetter) - Use revert v3: (Jason) - Update commit message v4 (Daniele): - fix checkpatch error in commit message.
