[PATCH v3 0/6] launch: direct: Disable qemu locking when opening drives readonly.
v2 -> v3:
- I addressed everything that Pino mentioned last time.
- It's tricky to get a stable run when multiple copies of qemu are
involved, because the same cache files get overwritten by parallel
libguestfs. So I changed the names of the cache files to include
the qemu binary key (size, mtime), which removes this conflict.
This is in new patch 4/6.
Rich.

[PATCH v2 0/5] launch: direct: Disable qemu locking when opening drives readonly (RHBZ#1417306)
Patches 1-4 are almost the same as they are when previously posted
here:
https://www.redhat.com/archives/libguestfs/2017-September/msg00039.html
Patch 5 actually uses the mandatory locking test to turn off locking
in the narrow case where a drive is opened readonly, and then only for
the drive being inspected.
Passes ordinary tests (‘check-direct’ and ‘check-valgrind-direct’).
Rich.

[PATCH 0/4] lib: qemu: Add test for mandatory locking.
The patch I posted last week to disable mandatory locking for readonly
drives
(https://www.redhat.com/archives/libguestfs/2017-September/msg00013.html)
was wrong in a couple of respects. Firstly it didn't work, which I
didn't detect because my tests were testing the wrong thing. Oops.
Secondly it used a simple version number check to detect qemu binaries
implementing mandatory locking.
