Subject: [PATCH 04/12] fuse2fs: quiet down EXT2_ET_RO_FILSYS errors

From: Darrick J. Wong <djwong@...nel.org>

If an fs update fails because the ext2_filsys is opened in readonly
mode, just return EROFS and don't log that.  This prevents unnecessary
spew for norecovery mounts.

Fixes: 81cbf1ef4f5dab ("misc: add fuse2fs, a FUSE server for e2fsprogs")
