f6c912dd0c Correctly set BUS_SPACE_MAXSIZE in all the busdma backends.
It was bogusly set to 64 * 1024 or 128 * 1024 because it was
bogusly reused in the BUS_DMAMAP_NSEGS definition.

48d4ffc119 - The interlock was not being droped in nfs_flush() if the first part of
an if clause was true.  Break the two clauses out into seperate statements
   since they require different actions.

7e734c4149 When doing cleanup of excessive buffers in bdwrite (see kern/vfs_bio.c
delta 1.371) we must ensure that we do not get ourselves into a
recursive trap endlessly trying to clean up after ourselves.

74f3809a19 Change the field used to test whether the superblock has been updated
from the filesystem size field to the filesystem maximum blocksize
field. The problem is that older versions of growfs updated only the
new size field and not the old size field. This resulted in the old
(smaller) size field being copied up to the new size field which
caused the filesystem to appear to fsck to be badly trashed.

This also adds a sanity check to ensure that the superblock is not
being updated when the filesystem is mounted read-only. Obviously
such an update should never happen.

e088615df0 Add a new subcommand to pccardc(8), "dumpcisfile", which reads a CIS
structure from a file instead of a PC-CARD itself before parsing and
dumping it. (E.g. useful when you get a CIS file from a manufacturer
which fixes they broken card's CIS, and add it to the pccard quirks.)

0f98df2956 Fix a long-standing bug where if the package being deleted had no
post-deinstall script, the variable intended to hold the name of that
script would be used uninitialized.  In some cases, fexists() would
succeed, causing pkg_delete to try to chmod +x it, then execute it,
resulting in bizarre error messages such as:

.//: Permission denied

This bug would normally only occur when multiple packages were
specified on the command line; otherwise post_script would be located
in a previously unused part of the stack, and implicitly (but quite
accidentally) initialized to all-zeros.

3a7053cb60 Prevent large files from monopolizing the system buffers. Keep
track of the number of dirty buffers held by a vnode. When a
bdwrite is done on a buffer, check the existing number of dirty
buffers associated with its vnode. If the number rises above
vfs.dirtybufthresh (currently 90% of vfs.hidirtybuffers), one
of the other (hopefully older) dirty buffers associated with
the vnode is written (using bawrite). In the event that this
approach fails to curb the growth in it the vnode's number of
dirty buffers (due to soft updates rollback dependencies),
the more drastic approach of doing a VOP_FSYNC on the vnode
is used. This code primarily affects very large and actively
written files such as snapshots. This change should eliminate
hanging when taking snapshots or doing background fsck on
very large filesystems.

Hopefully, one day it will be possible to cache filesystem
metadata in the VM cache as is done with file data. As it
stands, only the buffer cache can be used which limits total
metadata storage to about 20Mb no matter how much memory is
available on the system. This rather small memory gets badly
thrashed causing a lot of extra I/O. For example, taking a
snapshot of a 1Tb filesystem minimally requires about 35,000
write operations, but because of the cache thrashing (we only
have about 350 buffers at our disposal) ends up doing about
237,540 I/O's thus taking twenty-five minutes instead of four
if it could run entirely in the cache.
