From: Christoph Hellwig Date: Thu, 31 Aug 2023 05:29:40 +0000 (+0200) Subject: NFS: switch back to using kill_anon_super X-Git-Tag: v6.6.17~4049^2 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5069ba84b5e67873a2dfa4bf73a24506950fa1bf;p=platform%2Fkernel%2Flinux-rpi.git NFS: switch back to using kill_anon_super NFS switch to open coding kill_anon_super in 7b14a213890a ("nfs: don't call bdi_unregister") to avoid the extra bdi_unregister call. At that point bdi_destroy was called in nfs_free_server and thus it required a later freeing of the anon dev_t. But since 0db10944a76b ("nfs: Convert to separately allocated bdi") the bdi has been free implicitly by the sb destruction, so this isn't needed anymore. By not open coding kill_anon_super, nfs now inherits the fix in dc3216b14160 ("super: ensure valid info"), and we remove the only open coded version of kill_anon_super.
