Subject: afs: Rearrange afs_select_fileserver() a little
X-Git-Tag: v4.19~1607^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=16280a15be751b9994e94c5dc944e93fa4293199;p=platform%2Fkernel%2Flinux-rpi.git

afs: Rearrange afs_select_fileserver() a little

Rearrange afs_select_fileserver() a little to put the use_server chunk
before the next_server chunk so that with the removal of a couple of gotos
the main path through the function is all one sequence.
