Subject: afs: Handle the VIO and UAEIO aborts explicitly
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=eb8eae65f0c713bcef84b082aa919f72c3d83268;p=linux.git

afs: Handle the VIO and UAEIO aborts explicitly

When processing the result of a call, handle the VIO and UAEIO abort
specifically rather than leaving it to a default case.  Rather than
erroring out unconditionally, see if there's another server if the volume
has more than one server available, otherwise return -EREMOTEIO.
