Red Hat Bugzilla – Bug 155544
requeued IO does not have BIO_RW_FAILFAST set.
Last modified: 2007-11-30 17:11:04 EST
dm_bio_restore(), called just before requeuing, restores and overwrites our bio
flags. Attached patchlet fixes this.
Created attachment 113463 [details]
Move setting BIO_RW_FAILFAST to map_io()
where does the overwriting happen?
bio_record.h doesn't touch bi_rw
Brown paper bag. You're right. I got confused by the setting of bi_flags, but
bi_rw_failfast is in a different field as you correctly point out; maybe I was
looking for bugs a little bit _too_ hard.
Closing bug, patch not needed ;)
