we would have to zero it anyway. In the case that inode table was

libext2fs: don't mark the superblock as dirty if the fs was opened r/o

If the file system is read/only opened with a backup superblock, and
the file system has uninit_bg enabled, the super block must not be
marked as dirty; otherwise, ext2fs_close() will call ext2fs_flush(),
which will fail, since the file descriptor for the block device was
opened read/only, and then the file descriptor won't actually be
closed.

This is normally not a problem since most of the time the program will
exit shortly after calling ext2fs_close(), and many programs don't
bother checking the error return from ext2fs_close(), especially if
the file system was opened read/only.

A big exception to this is e2fsck, since it opens and close the file
systems during its startup, and to make matters worse, registers an
error handler which will noisly complain about the failed writes
caused by ext2fs_flush().

Fix this by not marking the superblock as dirty if the file system was
opened read/only.  The changes to the block group descriptors to clear
the uninit bits will still happen, so that e2fsck -n will properly
scan the whole file system.  However, those changes will get dropped
when the file system handle is closed.

libext2fs, libe2p: Reserve RO_COMPAT_REPLICA feature

The replica is a feature which stores multiple copies of the key
metadata blocks so a single block failure in failure-prone media
(read: certain types of flash storage) doesn't take out the entire
file system.

Discussion on the upstream list proved not to be very positive on this
feature; the arguments were that it added complexity that wasn't
warrented, since common practice in industry is to insist on reliable
media, and if media is unreliable, you're kind of toast anyway (unless
the file system is being used as the back-end store of a cluster file
system where checksuming and data replication is happening above the
local disk file system level).  So, this feature is being developed
out of tree.

We reserve the code points so that other people won't accidentally
step on them.  Since it's not upstream, it's a soft reservation, but
it's not like we have any shortage of RO_COMPAT features.  We are a
bit more tight on reserved inodes, but EXT2_BOOT_LOADER_INO and
EXT2_UNDEL_DIR_INO are not currently used anywhere, and
EXT2_EXCLUDE_INO is a reservation for another out-of-tree feature.
There are no features currently being discussed which require a
reserved inode, but if a need were to arise, we can claw back code
point reservations that were never used or not in tree, as those will
always be considered lower priority than in-tree features.
