a7265d71c6 This commit adds support for default signal actions for SIGSTOP, SIGSTP, and SIGCONT.
Squashed commit of the following:

    Add procfs support to show stopped tasks.  Add nxsig_action() to solve a chicken and egg problem:  We needed to use sigaction to set default actions, but sigaction() would refuse to set actions if the default actions could not be caught or ignored.

    sched/signal:  Add configuration option to selectively enabled/disable default signal actions for SIGSTOP/SIGSTP/SIGCONT and SIGKILL/SIGINT.  Fix some compilation issues.

    sched/sched:  Okay.. I figured out a way to handle state changes that may occur while they were stopped. If a task/thread was already blocked when SIGSTOP/SIGSTP was received, it will restart in the running state.  I will appear that to the task/thread that the blocked condition was interrupt by a signal and returns the EINTR error.

    sched/group and sched/sched:  Finish framework for continue/resume logic.

    sched/signal:  Roughing out basic structure to support task suspend/resume

07f441eecb Missing some conditional logic for cases where mountpoint procfd entries excluded. 2017-10-27 06:06:20 -06:00
Gregory Nutt
ea13e24392 Correct a problem that was causing an apparent directory to be reported as a file instead of a directory by opendir.
This happened after adding these three new procfs entries:

  fs/block
  fs/mount
  fs/usage

Of course, there is no directory fs in this case, only three files that have fs/ in their relative pathnames.  The logic was detecting that fs was the name of the enty to report, but it was then declaring that fs was a file (because fs/block is of type file).

This was fixed by adding a check for matching lenghts.  i.e., if strlen(fs) != strlen(fs/block), then report fs as a directory instead of a file.
