+Subject: bcachefs: bch2_ioctl_subvolume_destroy() fixes
+
+From: Kent Overstreet <kent.overstreet@linux.dev>
+
+[ Upstream commit 707549600c4a012ed71c0204a7992a679880bf33 ]
+
+bch2_evict_subvolume_inodes() was getting stuck - due to incorrectly
+pruning the dcache.
+
+Also, fix missing permissions checks.
