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.
proper file attribute (a.k.a. "resource fork") is picked up when
the filehandle is mapped back to filesystem object.
This should make attributes working on NFS-exported NTFS filesystems
or other layered filesystems using filehandles.
also fixes bug introduced in previous commit - the check for VBAD device node
added in rev 1.20 was accidentaly run AFTER v_specinfo was touched,
making the check useless
default, as the copyright on the main file (ffs_softdep.c) is such
that is has been put into gnusrc. options SOFTDEP will pull this
in. This code also contains the trickle syncer.
Bump version number to 1.4O
VOP__UNLOCK() macros, g/c VOP__LOCK()
add some comments
use LK_RETRY flag as appropriate
g/c the FreeBSD vnode_pager_uncache() staff, as was done in FreeBSD tree a while
ago (actually, when they merged the first round of NetBSD patches)
use VN_LOCK() & VOP__UNLOCK() consistently throughout the code instead
of vn_lock() and VOP_UNLOCK()
minor whitespace changes
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().
guard the setting and checking of i_usecount by simplelock; as
situation where there would be several users of same ntnode is
extremery rare, it's not worth the efford to change the code to
hold the (exclusive) lock only when it's needed
* in struct fnode, g/c f_dev & f_type (former is already in ntnode,
latter is in parent vnode), move f_devvp from struct fnode into
struct ntnode (no reason this should be copied in each fnode)
* f_lock is only needed for FreeBSD (for their totally disgusting
and insane way of doing generic vnode locking)
* g/c f_mp, it was write-only
* some comments added
is mounted and all ntfs volumes share it; the space occupied by the
table is freed upon last ntfs volumen umount. Saves 128KB for every
ntfs volume mounted.
XXX for now, read just first 256 entries - no more would be currently used
anyway
