chs ea6ddab6a8 the work-around in rev. 1.37 (turn off async) wasn't enough to prevent
hangs under heavy load.  so we now apply the more extreme version:
make MFS mounts "sync".  fixes PRs 17128 and 17321.

chs eecf9e208a fix PR 15299 by making MFS filesystems not be "async".
in the longer term, MFS needs to be made a lot more VM-friendly.

chs adf5d360a7 add a new VFS op, vfs_reinit, which is called when desiredvnodes is
adjusted via sysctl.  file systems that have hash tables which are
sized based on the value of this variable now resize those hash tables
using the new value.  the max number of FFS softdeps is also recalculated.

convert various file systems to use the <sys/queue.h> macros for
their hash tables.

thorpej 5b35dc8136 When unmounting a file system, acquire the syncer_lock before
vfs_busy'ing just before the dounmount() call.  This is to avoid
sleeping with the mountlist_slock held -- but we must acquire
syncer_lock before vfs_busy because the syncer itself uses
syncer_lock -> vfs_busy locking order.

cgd 4dddddfe62 fix bug (pointed out as sequence point violation warning with current-ish gcc)
caused by use of makedev(major,minor++).  makedev() now (since 32-bit
dev_t conversion) evaluates its second argument twice.

simonb 831fce13ac In mfs_start(), move the handling of outstanding I/O requests to before
the check for unmounting the filesystem.

Appears to fix kern/10122 from Hitoshi Matsunawa.

thorpej 5026e056e2 Back out previous change; there is something Seriously Wrong. 2000-05-19 20:42:20 +00:00
thorpej dd494c1a6c Redo the way MFS does I/O to the server's address space. Instead of
queueing up buffers and awakening the MFS server process to do the I/O,
we do the I/O to the server process's address space directly using
facilities provided by UVM.

This makes it possible for buffers attempting to flush out while the
MFS is being unmounted to actually do the I/O, where before it would
fail if the server process wasn't in the MFS idle loop (i.e. had been
signaled and was attempting to exit).

Should fix kern/10122 (I can no longer reproduce the problem described
in the PR when running with these changes), and any number of other
MFS-related complaints made by people over time.

thorpej 6d7f14dc5d Record the proc directly, not the pid, of the MFS server process,
and nuke the spare fields in the mfsnode.

jdolecek 03efc0b2b7 Add new VFS op routine - vfs_done and call it on filesystem detach
in vfs_detach(). vfs_done may free global filesystem's resources,
typically those allocated in respective filesystem's init function.
Needed so those filesystems which went in via LKM have a chance to
clean after themselves before unloading.

For each leaf filesystem, add appropriate vfs_done routine.

Also remember how many times ffs_init() was called and do
the appropriate initialization on first call only. In ffs_done(),
destroy the resources when called by the last user of ffs code.
Change mfs to call ffs_init()/ffs_done() appropriately.

wrstuden 862a56e88b Modify vfsops to seperate vfs_fhtovp() into two routines. vfs_fhtovp() now
only handles the file handle to vnode conversion, and a new call,
vfs_checkexp(), performs the export verification.

cgd 651b44e211 Rework the way kernel include files are installed. In the new method,
as with user-land programs, include files are installed by each directory
in the tree that has includes to install.  (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.)  The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change.  Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

cgd 90688fce27 Change the second and third args to struct vfsops' (*vfs_mount)() to
'const char *', and 'void *', respectively.  The second arg is taken directly
from user arguments, and is const there, so must be const in the prototypes
and functions.  The third arg is also taken directly from user arguments.
It doesn't have to be changed, but since it's cleaner to keep the type
the same as the user arg's type, and I'm already making the 'const char *'
change...
