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.
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. This fixes random panics
when LKM for filesystem using pools was loaded and unloaded several
times.
For each leaf filesystem, add appropriate vfs_done routine.
about ISO9660 file system structure), and cd9660_extern.h (which now
contains the definitions and data structures used by the kernel).
There's lots of other stuff scattered around this code that should go
into cd9660_extern.h, but doesn't need to right now. This changed patterned
on ffs, which has 'fs.h' which describes the FS structure, and ffs_extern.h
for kernel-internals gunk. Now libsa can include iso.h without the nasty
hack that was there before.
