8.2-STABLE, git id bc00e44d, svn r230835, some irrelevant
local modifications.
>Description:
With my most recent update, I am unable to destroy zfs
snapshots without using -R. This makes me unhappy, since -R
is a big hammer. This is also affect automatic deletion of
local snapshots provided by the sysutils/zfs-periodic port I'm
using; it (quite sanely) doesn't use -R.
>How-To-Repeat:
$ zfs snapshot pool@snapshot
$ zfs destroy -v pool@snapshot
will destroy pool@snapshot
will reclaim 0
[Exit 1 ]
$ zfs list pool@snapshot
NAME USED AVAIL REFER MOUNTPOINT
pool@snapshot 0 - 35K -
>Fix:
Patch that fixes the issue below; it's based on the git id
bc00e44d/svn r230835 that I'm currently running. The issue is the use
of an uninitialized variable "err".
