Message-Id: <20200824061712.195654-7-ebiggers@kernel.org> Date: Sun, 23 Aug 2020 23:17:10 -0700 From: Eric Biggers <ebiggers@...nel.org> To: linux-fscrypt@...r.kernel.org Cc: linux-ext4@...r.kernel.org, linux-f2fs-devel@...ts.sourceforge.net, linux-mtd@...ts.infradead.org, ceph-devel@...r.kernel.org, Jeff Layton <jlayton@...nel.org> Subject: [RFC PATCH 6/8] ubifs: use fscrypt_prepare_new_inode() and fscrypt_set_context() From: Eric Biggers <ebiggers@...gle.com> Convert ubifs to use the new functions fscrypt_prepare_new_inode() and fscrypt_set_context(). Unlike ext4 and f2fs, this doesn't appear to fix any deadlock bug. But it does shorten the code slightly and get all filesystems using the same helper functions, so that fscrypt_inherit_context() can be removed.
