It's pretty normal style: define a flags variable for any sort of bitops state that might show up, and then give the actual bits a meaningful name. There's almost no users of using a magic numberic value with atomic bitops. Besides being the usual and thus easier to read style it's also good future proofing. > > It would be good to just sort out the registered and co variables > > here before the RCU changes, as in: > > > > http://git.infradead.org/users/hch/scsi.git/commitdiff/6372d9f62c83acb30d051387c40deb4dbdcaa376 > > Why not just keep this patch squashed into the relevant commit in the > context of the larger RCU conversion..? Because the logic in and aroudn core_scsi3_pr_seq_non_holder right now is rather confusing. So before doing changes to it it's better to clean it up first, document that cleanup in a standalon patch and then apply the logic change on top. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
