In r322258 I made p1003_1b.aio_listio_max a tunable. However, further investigation shows that there was never any good reason for that limit to exist in the first place. It's used in two completely different ways: * To size a UMA zone, which globally limits the number of concurrent aio_suspend calls. * To artifically limit the number of operations in a single lio_listio call. There doesn't seem to be any memory allocation associated with this limit. This change does two things: * Properly names aio_suspend's UMA zone, and sizes it based on a new constant. * Eliminates the artifical restriction on lio_listio. Instead, lio_listio calls will now be limited by the more generous max_aio_queue_per_proc. The old p1003_1b.aio_listio_max is now an alias for vfs.aio.max_aio_queue_per_proc, so sysconf(3) will still work with _SC_AIO_LISTIO_MAX.

For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information).
The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7) and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables.
The buildkernel and installkernel targets build and install
the kernel and the modules (see below). Please see the top of
the Makefile in this directory for more information on the
standard build targets and compile-time flags.
Building a kernel is a somewhat more involved process. See build(7), config(8), and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information.
Note: If you want to build and install the kernel with the
buildkernel and installkernel targets, you might need to build
world before. More information is available in the handbook.
The kernel configuration files reside in the sys/<arch>/conf
sub-directory. GENERIC is the default configuration used in release builds.
NOTES contains entries and documentation for all possible
