I've also queued both commits for 5.15. 5.10 doesn't need either, > since it always hands decompression off to the workqueue. Thanks for the effort! btw, just correct a bit 5.15.y also has commit 648f2de053a8 ("erofs: use workqueue decompression for atomic contexts only"), so upstream commit 12d0a24afd9e ("erofs: Fix detection of atomic context") upstream commit c99fab6e80b7 ("erofs: fix atomic context detection when !CONFIG_DEBUG_LOCK_ALLOC") are also needed for 5.15.y.
