This patch set removes the FreeBSD file descriptors. The VFS is no

LibBSD for
these applications. Using the media01 test case for the arm/lpc32xx
BSP as a
benchmark, the heap usage dropped from 14.3MiB to 10.2MiB. The "_BSD
bufdaemon", "_BSD vnlru", "_BSD syncer", and "_BSD bufspacedaemon-"
tasks are
no longer present in media01. The code size is reduced by about
8KiB. The
data size is reduced by about 30KiB. The throughput with a simple
FTP test
increased by about 1%.
The "Remove FreeBSD file descriptors" change removes more lines than
there are
added.
This change makes it easier to port the NFS support to the master
branch since
now the changes are more localized.
I have a target with only 8MiB of RAM (for code and data). So, this
patch set is not just a micro optimization.
This pending patch set is currently a blocker for me. I would like to
work on the NTP daemon integration and an update of the libbsd master
branch to a more recent FreeBSD version. This patch set just restores
what worked well for several years.
did you have time to review this patch set in the meantime? The NTP
client no longer crashes with this patch set.
