mainlining shenanigans

Currently 'pooled' services hold a reference on the pool_map, and 'unpooled' services do not. svc_destroy() uses the presence of ->svo_function (via svc_serv_is_pooled()) to determine if the reference should be dropped. There is no direct correlation between being pooled and the use of svo_function, though in practice, lockd is the only non-pooled service, and the only one not to use svo_function. This is untidy and would cause problems if we changed lockd to use svc_set_num_threads(), which requires the use of ->svo_function. So change the test for "is the service pooled" to "is sv_nrpools > 1". This means that when svc_pool_map_get() returns 1, it must NOT take a reference to the pool. We discard svc_serv_is_pooled(), and test sv_nrpools directly. Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: Chuck Lever <chuck.lever@oracle.com> |

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.
