It would probably be better to declare these one line per entry, like:
static const char const *quota_names[MAXQUOTAS] = {
[USRQUOTA] = "User",
[GRPQUOTA] = "Group",
[PRJQUOTA] = "Project",
};

Unfortunately, this has the potential for a serious data corruption,
since ext2_super_block is the on-disk superblock and not in-memory.
If MAXQUOTAS is ever changed then this will overflow s_overhead_blocks
on disk and change the size of the superblock, which will also break
the superblock checksum.
Unfortunately, I don't see an easy way to fix this without having some
kind of indirection array or function that records the offsets of these
fields in the superblock, because both s_{usr,grp}_quota_inum and s_overhead_blocks have been in use for long enough that it isn't easy
to change them. The benefit is that with an indirection array there is
no need to reserve contiguous space for all future quota types.

This will need to be a helper function instead of an array dereference.
The other alternative would be something like:
inump = &fs->super->s_quota_inum[ext2fs_quota_type_offset[qtype]];
and then there is something like the following is done:
int ext2fs_quota_type_offset[] = {
[USRQUOTA] = 0,
[GRPQUOTA] = 1,
[PRJQUOTA] = 3,
};

It might be better to name this "is_reserved_quota_inum()" to match
the other function, or even better would be to put "quota" near the
start so they are more easily found, like quota_inum_is_reserved()
and quota_inum_is_super() or similar.

Should there be some kind of sanity check that MAXQUOTAS is < 32?
I guess most compilers will complain about << 32 for an unsigned int,
but it would be good to make sure.

"type2ino()" is a very generic function name. At least using
quota_type2ino() would make it more clear that this relates to
quota. Secondly, "qtype" should be an enum that declares USRQUOTA
and GRPQUOTA, and then uses this consistently throughout the code.

It isn't the fault of this patch, but I'd really prefer to see
all of these constants put "QUOTA" at the start, so they sort
together, like QUOTA_USR{,_BIT}, QUOTA_GRP{,_BIT}, QUOTA_ALL_BIT.
Is there some dependency on the upstream kernel or quota-tools
package that would recommend against this change?
It should definitely be in a separate patch from this one.
