Subject: fakestat should preclude afsdb lookups too
X-Git-Tag: openafs-devel-1_5_72~45
X-Git-Url: https://git.michaelhowe.org/gitweb/?a=commitdiff_plain;h=682db4d64d550af86dc5a09786e050c6a98ffb0c;p=packages%2Fo%2Fopenafs.git

fakestat should preclude afsdb lookups too

macos tries to look up ._foo stuff. correctly identify those (mvstat 2, not
1) and also use tryEvalOnly to preclude AFSDB lookups
