Subject: block: Handle partition read errors more consistently
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=98d8ba69ff1ac168e73ac509228c4701bf6c3b87;p=linux.git

block: Handle partition read errors more consistently

Set p->v to NULL if we try to read beyond the end of the disk, just like
we do if we get an error returned from trying to read the disk.
