      module/decompress: Fix error checking on zstd decompression · fadb74f9
      Lucas De Marchi authored
      While implementing support for in-kernel decompression in kmod,
      finit_module() was returning a very suspicious value:
      
      	finit_module(3, "", MODULE_INIT_COMPRESSED_FILE) = 18446744072717407296
      
      It turns out the check for module_get_next_page() failing is wrong,
      and hence the decompression was not really taking place. Invert
      the condition to fix it.

      fork, vhost: Use CLONE_THREAD to fix freezer/ps regression · f9010dbd
      Mike Christie authored
      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
      process that does the VHOST_SET_OWNER ioctl, and has vhost_worker call
      get_signal to support SIGKILL/SIGSTOP and freeze signals. Note that
      SIGKILL/STOP support is required because CLONE_THREAD requires
      CLONE_SIGHAND which requires those 2 signals to be supported.
      
      This is a modified version of the patch written by Mike Christie
      <michael.christie@oracle.com> which was a modified version of patch
      originally written by Linus.
      
      Much of what depended upon PF_IO_WORKER now depends on PF_USER_WORKER.
      Including ignoring signals, setting up the register state, and having
      get_signal return instead of calling do_group_exit.
      
      Tidied up the vhost_task abstraction so that the definition of
      vhost_task only needs to be visible inside of vhost_task.c.  Making
      it easier to review the code and tell what needs to be done where.
      As part of this the main loop has been moved from vhost_worker into
      vhost_task_fn.  vhost_worker now returns true if work was done.
      
      The main loop has been updated to call get_signal which handles
      SIGSTOP, freezing, and collects the message that tells the thread to
      exit as part of process exit.  This collection clears
      __fatal_signal_pending.  This collection is not guaranteed to
      clear signal_pending() so clear that explicitly so the schedule()
      sleeps.
      
      For now the vhost thread continues to exist and run work until the
      last file descriptor is closed and the release function is called as
      part of freeing struct file.  To avoid hangs in the coredump
      rendezvous and when killing threads in a multi-threaded exec.  The
      coredump code and de_thread have been modified to ignore vhost threads.
      
      Remvoing the special case for exec appears to require teaching
      vhost_dev_flush how to directly complete transactions in case
      the vhost thread is no longer running.
      
      Removing the special case for coredump rendezvous requires either the
      above fix needed for exec or moving the coredump rendezvous into
      get_signal.
