fvdl 81ba8e7ff7 Adapt for VOP_FSYNC parameter change.
Implement range fsync for FFS. Note: not yet implemented for the
SOFTDEP case.

fvdl ce4bcf47f3 Do not call MALLOC with M_WAITOK while holding the "lock". Thanks to
Ethan Solomita for the reminder.

Mark the parent vnode lock as recursive while flushing pagedeps. XXX.
Should fix kern/10564.

fvdl d09958adad Due to popular demand, change vinsheadfree to ungetnewvnode to make
the name clearer. No functional change.

fvdl bba2403203 In ffs_vget, do not hold ufs_haslock across the call to getnewvnode.
We may sleep in it, or even recurse, with softdeps. Instead, grab
the lock later, but check if noone else has beaten us to the VFS_VGET
operation, and if so, roll back getnewvnode using vinsheadfree, and
just return.

pk 88b0328aca We shouldn't be defining DEBUG and DIAGNOSTIC on our own; these may have
unwanted side-effects in the header files. For now, do the internal
#defines after including the headers.

matt 1b5bc7ce61 ignore the softdep flags when mounting and there's no softdep in the kernel. 2000-06-16 00:30:15 +00:00
fvdl 4f11634756 Allow MNT_SOFTDEP to be passed in via the mount(2) system call, do not
require it to be set via tunefs(8). Silently ignore it when doing
an update mount of a writeable filesystem, the FFS/softdep code isn't ready
for this yet.

mycroft 64f5a574a7 In ffs_update():
* Move the clearing of IN_MODIFIED and IN_ACCESSED later, so they are not
  cleared if the bread() failed.
* Explicitly set waitfor to 0 in the softdep case, if IN_MODIFIED is not
  set (mirroring the bwrite()/bdwrite() decision).

mycroft 4db674fa50 According to Frank, buffers with dependencies *are* left on v_dirtyblks, so
remove the FSYNC_RECLAIM check and force them to be flushed.

mycroft d747ada9c2 Add a new inode flags called IN_ACCESSED. This used in place of IN_MODIFIED
to record that the atime was updated.  In ffs_update(), we only do synchronous
writes if something *other* than the atime was changed.

mycroft 941524439a Never call softdep_sync_metadata() in the FSYNC_RECLAIM case. Any pending
blocks are detached from the vnode at this point.  When the dependencies are
broken to enable writing the blocks, the vnode will be regenerated.  (The only
reason we sync buffers in this case is that they have to be detached from the
vnode.)

mycroft c47adf55e0 In ffs_fsync(), remove the FSYNC_RECLAIM special case, so that it properly
waits for pending buffers, and doesn't throw away time stamp updates.

mycroft 4fc7b946c2 When unwinding a failed allocation, make sure to nuke the unwound block from
the vnode's block list.  This fixes `itrunc3' panics (at least in some cases;
further testing is needed) and prevents further lossage later on.

mycroft 4656dfd24f Add a new function to remove extra buffers when truncating a file. This is
more generic than the vinvalbuf(V_SAVEMETA) case, avoiding synchronous
operations when truncating to a non-zero length.

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.

jdolecek c78399fc88 Add a new sysctl variable vfs.ffs.log_changeopt - if this is true,
an optimalization strategy change is logged into syslog. Default

change to only log the change if kernel is compiled with DEBUG.

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.

fvdl 563d336e44 Don't immediately return in ffs_fsync if there appears to be no data
to flush if it's a vnode on a softdep filesystem. softdep_sync_metadata
may still need to do some work.
2000-03-14 13:06:29 +00:00
perseant 61fa9e1409 Move vinvalbuf's check for dirty blocks into ffs_fsync, to ensure that
mode and ownership bits are flushed to disk before the vnode is
reclaimed.

The check, introduced in the softdep merge, assumes that if no blocks
are dirty, no file data *or metadata* needs to be flushed to disk.  This
is true of ffs, but is not true of lfs, and may not be true of other
filesystems.

Tested by myself and Bill Squier <groo@cs.stevens-tech.edu>.

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().

call with F_FSCTL set and F_SETFL calls generate calls to a new

for F_SETFL and EOPNOTSUPP otherwise. Have all leaf filesystems
use genfs_fcntl().
