I find it clearer. Unless there's a style guide that disagrees, I'll leave this as-is. Cheers ^ permalink raw reply [flat|nested] 6+ messages in thread

Something like check_for_non_generic_match would be a lot better. Alan Stern ^ permalink raw reply [flat|nested] 6+ messages in thread

Something like > check_for_non_generic_match would be a lot better. Sure. I'll do a follow-up patch unless there's something requiring a respin. Greg, there's just the typo in this commit message, all the rest was ack'ed. Did you want to take care of that typo, or do you want me to respin?

Never make me hand-edit a patch, that ensures it will go to the end of the line :( ALso, your patches are not showing up as linked to each other, so they are all over the place in my mailbox. Please use something like git send-email or other tools that will properly link them to ensure I can see them correctly. thanks, greg k-h ^ permalink raw reply [flat|nested] 6+ messages in thread
