Subject: Windows: buf_RDRBuffersExist and cm_directIO
X-Git-Tag: upstream/1.8.0_pre1^2~1283
X-Git-Url: https://git.michaelhowe.org/gitweb/?a=commitdiff_plain;h=d3c04329a396cc82a71321bb209b783a1524018e;p=packages%2Fo%2Fopenafs.git

Windows: buf_RDRBuffersExist and cm_directIO

If 'cm_directIO' is true, then no RDR buffers exist.  Return immediately,
do not pass 'Go', and do not lock and walk the buffer hash table.
