[PATCH 11/19] gfs: use __bio_add_page for adding single page to bio

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

 



The GFS superblock reading code uses bio_add_page() to add a page to a
newly created bio. bio_add_page() can fail, but the return value is never
checked.

Use __bio_add_page() as adding a single page to a newly created bio is
guaranteed to succeed.

This brings us a step closer to marking bio_add_page() as __must_check.
