"bsdsort" and GNU sort will be the default "sort". When WITH_BSD_SORT
is set, BSD sort will be the default "sort" and GNU sort will be installed
as "gnusort".
with the major functionality and optimizations by Oleg Moskalenko.
It is compatible with the latest version of POSIX and the current GNU sort
version that we have in base. Beside this, it implements all the
functionality introduced in later versions of GNU sort. For now, it will
be installed as "bsdsort", keeping GNU sort as the default sort
implementation.
[ENOENT] A component of file_name does not name an existing file or
file_name points to an empty string.
[ENOTDIR] A component of the path prefix is not a directory, or the
file_name argument contains at least one non- <slash> character
and ends with one or more trailing <slash> characters and the last
pathname component names an existing file that is neither a
directory nor a symbolic link to a directory.
Add checks for the listed conditions, and set errno accordingly.
Update the realpath(3) manpage to mention SUS behaviour. Remove the
requirement to include sys/param.h before stdlib.h.

loaded as modules. Otherwise, when these MAC/PHY driver pairs are
compiled into a single module probing the PHY driver may fail. This

support for multiple boards to be built into one kernel (starting with
AT91RM9200 and expanding out from there).
There are two aspects to the sequential access optimization: (1) read ahead
of pages that are expected to be accessed in the near future and (2) unmap
and cache behind of pages that are not expected to be accessed again. This
revision changes both aspects.
The read ahead optimization is now more effective. It starts with the same
initial read window as before, but arithmetically grows the window on
sequential page faults. This can yield increased read bandwidth. For
example, on one of my machines, a program using mmap() to read a file that
is several times larger than the machine's physical memory takes about 17%
less time to complete.
The unmap and cache behind optimization is now more selectively applied.
The read ahead window must grow to its maximum size before unmap and cache
behind is performed. This significantly reduces the number of times that
pages are unmapped and cached only to be reactivated a short time later.
The unmap and cache behind optimization now clears each page's referenced
flag. Previously, in the case of dirty pages, if the containing file was
still mapped at the time that the page daemon examined the dirty pages,
they would be reactivated.
From a stylistic standpoint, this revision also cleanly separates the
implementation of the read ahead and unmap/cache behind optimizations.

Unlike other classes GEOM RAID can be set up from BIOS before install and
users are expecting it to be detected automatically.
