systems were repo-copied from sys/miscfs to sys/fs.
- Renamed the following file systems and their modules:
fdesc -> fdescfs, portal -> portalfs, union -> unionfs.
- Renamed corresponding kernel options:
FDESC -> FDESCFS, PORTAL -> PORTALFS, UNION -> UNIONFS.
- Install header files for the above file systems.
- Removed bogus -I${.CURDIR}/../../sys CFLAGS from userland

Add a vop_stdbmap(), and make it part of the default vop vector.2001-04-29T11:48:41ZPoul-Henning Kampphk@FreeBSD.org2001-04-29T11:48:41Zurn:sha1:b7ebffbc08b318c8896df13149761f167ecbf531
Make 7 filesystems which don't really know about VOP_BMAP rely
on the default vector, rather than more or less complete local
vop_nopbmap() implementations.

Add snapshots to the fast filesystem. Most of the changes support2000-07-11T22:07:57ZKirk McKusickmckusick@FreeBSD.org2000-07-11T22:07:57Zurn:sha1:f2a2857bb34f5525f21ad016c25b20348d7a1fab
the gating of system calls that cause modifications to the underlying
filesystem. The gating can be enabled by any filesystem that needs
to consistently suspend operations by adding the vop_stdgetwritemount
to their set of vnops. Once gating is enabled, the function
vfs_write_suspend stops all new write operations to a filesystem,
allows any filesystem modifying system calls already in progress
to complete, then sync's the filesystem to disk and returns. The
function vfs_write_resume allows the suspended write operations to
begin again. Gating is not added by default for all filesystems as
for SMP systems it adds two extra locks to such critical kernel
paths as the write system call. Thus, gating should only be added
as needed.
Details on the use and current status of snapshots in FFS can be
found in /sys/ufs/ffs/README.snapshot so for brevity and timelyness
is not included here. Unless and until you create a snapshot file,
these changes should have no effect on your system (famous last words).
Back out the previous change to the queue(3) interface.2000-05-26T02:09:24ZJake Burkholderjake@FreeBSD.org2000-05-26T02:09:24Zurn:sha1:e39756439c7255bc16ba14b7b991cb01ba1c93bd
It was not discussed and should probably not happen.
