This patch will return -EINTR instead of 1 if recovery is stopped. In case of ping_members() the return value will be checked if the error is -EINTR for signaling another recovery was triggered and the whole recovery process will come to a clean end to process the next one. Returning 1 will abort the recovery process and can leave the recovery in a broken state. It was reported with the following kernel log message attached and a gfs2 mount stopped working: "dlm: bobvirt1: dlm_recover_members error 1" whereas 1 was returned because of a conversion of "dlm_recovery_stopped()" to an errno was missing which this patch will introduce. While on it all other possible missing errno conversions at other places were added as they are done as in other places. It might be worth to check the error case at this recovery level, because some of the functionality also returns -ENOBUFS and check why recovery ends in a broken state. However this will fix the issue if another recovery was triggered at some points of recovery handling.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
