Note: The patch differs from the upstream commit: --- 1: 3eb96946f0be6 ! 1: 6a6f180aae691 block: make bio_check_eod work for zero sized devices @@ Metadata ## Commit message ## block: make bio_check_eod work for zero sized devices
+ commit 3eb96946f0be6bf447cbdf219aba22bc42672f92 upstream. + + This patch is a backport. + Since the dawn of time bio_check_eod has a check for a non-zero size of the device. This doesn't really make any sense as we never want to send I/O to a device that's been set to zero size, or never moved out of that. @@ Commit message the issue really goes back way before git history.
