nilfs2: use GFP_NOIO for bio_alloc instead of GFP_NOWAIT
Alberto Bertogli advised me about bio_alloc() use in nilfs: On Sat, 13 Jun 2009 22:52:40 -0300, Alberto Bertogli wrote: > By the way, those bio_alloc()s are using GFP_NOWAIT but it looks > like they could use at least GFP_NOIO or GFP_NOFS, since the caller > can (and sometimes do) sleep. The only caller is nilfs_submit_bh(), > which calls nilfs_submit_seg_bio() which can sleep calling > wait_for_completion(). This takes in the comment and replaces the use of GFP_NOWAIT flag with GFP_NOIO. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
