Series [01/17] zonefs: use bio_alloc in zonefs_file_dio_append | expand

Commit Message

Christoph Hellwig Jan. 26, 2021, 2:52 p.m. UTC
Given that drbd_md_io_bio_set is initialized during module initialization
and the module fails to load if the initialization fails there is no need
to fall back to plain bio_alloc.
