Subject: Fix traceaio with IO_CMD_{PREAD,PWRITE}
X-Git-Tag: release-4.6~56
X-Git-Url: https://sourceware.org/git/?a=commitdiff_plain;h=357968f8b57333ac423d2b589a7fbc30523d0836;p=systemtap.git

Fix traceaio with IO_CMD_{PREAD,PWRITE}

IOCB_CMD_PREADV was used twice, skipping logging of iovecs for
IOCB_CMD_PWRITEV.
