I committed a somewhat modified version of this patch. Also, I checked
the NetBSD code and while they tried to make a similar change they fail
to properly cast one of the arguments in the multiplication so NetBSD
doesn't actually fix the bug.
:The following disables a check which more than a few FreeBSD users
:have discovered breaks their soundcards (there's a PR about this
:too). Well, not breaks, but keeps from working. Explained in the
:comment. NetBSD does no such check and worked out-of-box with my
:card.
Committed, except note that your #ifdef cannot have a '-' in it... it's
actually two symbols instead of one. I replaced the '-' with an underscore
'_'.
:This patch to userland ppp significantly decreases the amount
:of CPU usage. I believe something like this is present in FreeBSD
:with a MFC, and it made a huge difference for me.
Committed.
:Another performance improver with my FreeBSD was to merge in
:the following based on -current, which in part, avoids fsync()ing
:the syslog file at every line during boot, which otherwise slows
:my boot by several seconds and makes my disk sound like a small
:jackhammer.
Committed. I just synchronized the whole program with FreeBSD-current.
:And finally, this patch to `mount' helps those of us who use
:tab-completion shells that append trailing slashes to directory
:names, so that one need not erase the trailing slash before
:entering, say, `mount -u /tmp/'
Committed (the FreeBSD version).
