... > Just a gentle ping on this patch. Any further comments or plans to pick it > up? Unfortunately your patch has not been picked up by our CI, now I re-run the test. In any case, your second patch can't be merged yet because your previous one(*) has been applied to the wrong branch from Christian while it should have gone through drm-intel-gt-next. Now we need to wait for a backmerge. In any case, if the tests succeed, I can already apply your first patch so that it gets included in the Wednesday's pull request. While the second patch, that is not a fix, has plenty of time and can wait the backmerge. Andi (*) 048832a3f400 ("drm/i915: Refactor shmem_pwrite() to use kiocb and write_iter")
