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.

Unfortunately it causes too much bloat (228 -> 72 bytes free) to

Instead, define a structure that contains all 4 buffers which must

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.

involving file removal or file update were not always being fully
committed to disk. The result was lost files or corrupted file data.
This change ensures that the filesystem is properly synced to disk
before the filesystem is down-graded.
This delta also fixes a long standing bug in which a file open for
reading has been unlinked. When the last open reference to the file
is closed, the inode is reclaimed by the filesystem. Previously,
if the filesystem had been down-graded to read-only, the inode could
not be reclaimed, and thus was lost and had to be later recovered
by fsck. With this change, such files are found at the time of the
down-grade. Normally they will result in the filesystem down-grade
failing with `device busy'. If a forcible down-grade is done, then
the affected files will be revoked causing the inode to be released
and the open file descriptors to begin failing on attempts to read.

semantics of the nfsm_reply() macro were changed so that the caller

but since the nfs cleanup, it hasn't done so in the case where
`error' is EBADRPC. Callers of this macro expect it to initialise

whatever junk was in *mrq (often a stale pointer to an old reply
