  file-posix: add drop-cache=on|off option (2019-03-13 10:54:55 +0000)

----------------------------------------------------------------
Pull request

 * Add 'drop-cache=on|off' option to file-posix.c.  The default is on.
   Disabling the option fixes a QEMU 3.0.0 performance regression when live
   migrating on the same host with cache.direct=off.
