jdolecek b0fb24279c change the lf_advlock() arguments from
int     lf_advlock __P((struct lockf **,
           off_t, caddr_t, int, struct flock *, int));
to

int     lf_advlock __P((struct vop_advlock_args *, struct lockf **, off_t));

This matches common usage and is also compatible with similar change
in FreeBSD (though they use u_quad_t as last arg).

jdolecek 166a3f16dd ext2fs_reload(), ext2fs_mountfs(): do devvp locking same way as ffs
this has not shown any good or bad effect, but might help narrow
some problems people seen with ext2fs reload (hi Soren!)

fvdl fa78158b15 Rearrange code around getnewvnode as was already done for ffs, to avoid

perseant f0728fdce1 Change the sementics of the last parameter from a boolean ("waitfor") to
a set of flags ("flags").  Two flags are defined, UPDATE_WAIT and
UPDATE_DIROP.

Under the old semantics, VOP_UPDATE would block if waitfor were set,
under the assumption that directory operations should be done
synchronously.  At least LFS and FFS+softdep do not make this
assumption; FFS+softdep got around the problem by enclosing all relevant
calls to VOP_UPDATE in a "if(!DOINGSOFTDEP(vp))", while LFS simply
ignored waitfor, one of the reasons why NFS-serving an LFS filesystem
did not work properly.

Under the new semantics, the UPDATE_DIROP flag is a hint to the
fs-specific update routine that the call comes from a dirop routine, and
should be wait for, or not, accordingly.

Closes PR#8996.

thorpej fa7d868ade Small cosmetic change. 2000-03-22 01:03:33 +00:00
jdolecek 89015c4648 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. 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.

enami fee96e1746 Check if the type of device node isn't VBAD before touching v_specinfo. If
the device vnode is revoked, the field is NULL and touching it causes null
pointer derefercence.

wrstuden e682a080e9 In spec_close(), if we're not doing a non-blocking close and VXLOCK is
not set, unlock the vnode before calling the device's close routine and
relock it after it returns. tty close routines will sleep waiting for
buffers to drain, which won't happen often times as the other side needs
to grab the vnode lock first.

Make all unmount routines lock the device vnode before calling VOP_CLOSE().

wrstuden 3bf14d81e9 Add support for fcntl(2) to generate VOP_FCNTL calls. Any fcntl
call with F_FSCTL set and F_SETFL calls generate calls to a new
fileop fo_fcntl. Add genfs_fcntl() and soo_fcntl() which return 0
for F_SETFL and EOPNOTSUPP otherwise. Have all leaf filesystems
use genfs_fcntl().

bouyer 466d1747ff memset ump->um_e2fs to 0 after malloc, it is bigger than SBSIZE and thus some
