search for: recalc_sigpending

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. This patch was modified from Eric Biederman <ebiederm at xmission.com> original patch. Signed-off-by: Mike Christie &lt...

The following patches made over Linus's tree fix the 2 bugs: 1. vhost worker task shows up as a process forked from the parent that did VHOST_SET_OWNER ioctl instead of a process under root/kthreadd. This was causing breaking scripts. 2. vhost_tasks didn't disable or add support for freeze requests. The following patches fix these issues by making the vhost_task task a thread under the
