I do think that if we're going to do this thing it should have 100%
coverage, and not have little exceptions because the volume of changes got
too high.

The number of places where you need IS_RDONLY_INODE() are encouragingly
small. It appears that all we need to do to get rid of it is to propagate
the file* down through the ext2 and ext3 xattr code. A NULL value will
need to be permitted because ext2_new_inode doesn't have a file*, and we've
already performed the check.

Sure, it's a largeish patch but it is very safe: if it compiles, it works.

Could you please work that with Andreas?

IS_RDONLY_INODE() is also used in intermezzo, but that doesn't compile any
more anyway.
