[PATCH 6/8] block: downgrade a bio_full call in bio_add_page

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



bio_add_page already checks that there is space in bi_size a little
earlier.  So after we failed to add to an existing segment, just check
that there is another one available instead of duplicating the bi_size
check.
