This is slightly different than my last report (involving
zfs_lookup/zfs_dirent). I still need to gather information from that
previous one.
Here is what I have on this one. Quoted so Thunderbird doesn't trash it:
> 1. Poudriere build startup, run for N=3D01,...,12 in parallel:
> a. mount tmpfs on /poudriere/data/.m/exp-10amd64-commit-test/N
> /poudriere/data/.m is a ZFS mount.
> b. cpdup /poudriere/data/.m/exp-10amd64-commit-test/ref to /poudri=
ere/data/.m/exp-10amd64-commit-test/N
> [1] c. mkdir -p /poudriere/data/.m/exp-10amd64-commit-test/N/.p
> 2. SIGINT during this phase:
> [2] a. umount -f all tmpfs
> b. cpdup processes are *not* killed. They continue running. Most o=
f them fail due to their dst tmpfs being gone.
> [3] c. A cpdup process managed to continue running. Since the tmpfs wa=
s gone it started trying to write to the ZFS mount under it. (/poudriere/=
data/.m)
