Hmm, I don't like the code in ext4_da_reserve_space even after your patch - the
retries are duplicated with the ones from ext4_da_write_begin and calling
write_inode_now from ext4_da_write_begin doesn't make too much sense either -
why not write all inodes with delayed allocation if we want to write something?

Actually, instead of retrying delayed allocation, I think it makes more sense
to just fall back to normal allocation. Attached patch does that and it also
allows me to completely fill user's quota.
