[Xenomai-core] [git pull v2] RTDM fixes and reworks

[Jan Kiszka]

[-- Attachment #1: Type: text/plain, Size: 3958 bytes --]

The following changes since commit 113ea4d56e8b215cb56ae7673013163ea5a5987d:
  Gilles Chanteperdrix (1):
        switchtest: increase stack sizes

are available in the git repository at:

  git://git.xenomai.org/xenomai-jki.git for-upstream


Changes in v2:
 - compat support for rttest device names
 - documented RTDM close procedure
 - internal rework of the close procedure
 - basic RTDM unit test, so far targeting at the close rework
 - some additional small cleanup patches

Beyond that series, there is now also our full /proc rework updated in
git, see

  git://git.xenomai.org/xenomai-jki.git queues/proc

I will send a separate pull request for that one later, either on top of
this (if there are no further concerns) or against master (it should
be orthogonal).

Ok, could you git-send-mail the patches to the list? Reviewing them in
the xenomai-git mailing list is not that convenient, I am afraid to miss
some of them.

One thing I did not see in your close test (but may have missed it, I
just can not find back the specific mail containing it), you should
check that, if a driver returns -EAGAIN, and open is called right after
close, the caller gets the same file descriptor.
