vhost_task_create is supposed to return the vhost_task or NULL on failure. This fixes it to return the correct value when the allocation of the struct fails.

This patch has the core work flush function take a worker. When we support multiple workers we can then flush each worker during device removal, stoppage, etc. Signed-off-by: Mike Christie <michael.christie at oracle.com> --- drivers/vhost/vhost.c | 24 +++++++++++++++--------- 1 file changed, 15 insertions(+), 9 deletions(-) diff --git a/drivers/vhost/vhost.c b/drivers/vhost/vhost.c

When get_pending detects the task has been marked to be killed we try to clean up the SIGKLL by doing a sigdelset and recalc_sigpending, but we still leave it in shared_pending. If the signal is being short circuit delivered there is no need to put in shared_pending so this adds a check in complete_signal.

The following patches were made over Linus tree. The patches fix 3 issues: 1. If a user performs LIO LUN unmapping before the endpoint has been cleared then we can end up trying to free a bogus tmf struct if the TMF is still exucuting when we do the unmap. 2. If vhost_scsi_setup_vq_cmds fails we can leave the tpg->vhost_scsi pointer set and we can end up trying to access a freed struct. 3.

The following patches were made over Linus tree and also apply over mst tree's vhost branch. The patches fix an issue where management operations like LUN mapping/unmapping and device addition hang for 30 seconds or up to N minutes depending on the device. The problem is that we use a global mutex to protect the list of tpgs but we hold that mutex during those management operations. So if you

In the next patches each vq might have different workers so one could have work but others do not. For net, we only want to check specific vqs, so this adds a helper to check if a vq has work pending and converts vhost-net to use it.

I've been doing a lot of the development on vhost-scsi the last couple of years, so per Michael T's suggestion this adds me as co-maintainer.

When switching from kthreads to vhost_tasks two bugs were added: 1. The vhost worker tasks's now show up as processes so scripts doing ps or ps a would not incorrectly detect the vhost task as another process. 2. kthreads disabled freeze by setting PF_NOFREEZE, but vhost tasks's didn't disable or add support for them. To fix both bugs, this switches the vhost task to be thread in the
