which small and/or nearly full filesystems would fail with `file
system full' messages when trying to replace a number of existing
files (for example during a system installation). When the allocation
routines are about to fail with a file system full condition, they
make a call to softdep_request_cleanup() which attempts to accelerate
the flushing of pending deletion requests in an effort to free up
space. In the face of filesystem I/O requests that exceed the
available disk transfer capacity, the cleanup request could take
an unbounded amount of time. Thus, the softdep_request_cleanup()
routine will only try for tickdelay seconds (default 2 seconds)
before giving up and returning a filesystem full error. Under typical
conditions, the softdep_request_cleanup() routine is able to free
up space in under fifty milliseconds.

operation. The vgonel() code has always called vclean() but until we
started proactively freeing vnodes it would never actually be called with
a dirty vnode, so this situation did not occur prior to the vnlru() code.
Now that we proactively free vnodes when kern.maxvnodes is hit, however,
vclean() winds up with work to do and improperly generates the warnings.

because the buffers we use could end up spanning a 64k boundary.
Unfortunately it causes too much bloat (228 -> 72 bytes free) to
just reinstate the old malloc() function.
Instead, define a structure that contains all 4 buffers which must
not cross 64k boundaries. We allocate a 64k-aligned instance in
main() using the magic that was in the old boot2 malloc() function.
This brings the free space down to 168 bytes, but that is still
better than it was before revision 1.35 (136 bytes).

at insert time. When asking gibbs for approval for an MFC, this was
his reply:
1) It leaks memory if it can't allocate a path.
2) It defers allocation of aic->path until the call to scan the
bus. This means the path may be NULL when an interrupt occurs
prior to the call to scan the bus (stray bus reset for instance),
which will lead to a panic.
3) The driver in current doesn't recover from the failure to allocate
aic->path. The driver doesn't check during normal operation if
the path is NULL, so again a panic will result.
4) aic_cam_rescan calls malloc with M_WAITOK. aic_cam_rescan is called
from attach where it isn't necessarily safe to sleep.
5) And most importantly, it co-opts the xpt_periph from the driver level.
This was never part of the design (xpt_periph used to be static). Making
a call of this type may completely confuse the XPT if other XPT operations
are ongoing.
In the long term, Justin and Warner agreed to implement solution where
CAM itself will initiate the bus rescan if a new bus is added. For
the time being (and in particular in light of the upcoming 4.5
release), we now have camcontrol available on the boot floppy, and can
have pccardd initiate the rescan through it.
