Subject: Merge zvol.c changes from PSARC 2010/306 Read-only ZFS pools
X-Git-Url: https://git.camperquake.de/gitweb.cgi?a=commitdiff_plain;h=a4430fce691d492aec382de0dfa937c05ee16500;hp=a4430fce691d492aec382de0dfa937c05ee16500;p=zfs.git

Merge zvol.c changes from PSARC 2010/306 Read-only ZFS pools

The changes to zvol.c were never merged from the last onnv_147
bulk update.  This was because zvol.c was largely rewritten
for Linux making it fairly easy to miss these sorts of changes.

This causes a regression when importing a zpool with zvols
read-only.  This does not impact pool which only contain
filesystem datasets.
