1bff00ecec Destroy extattr lock when destroying extattrs associated with the 
mountpoint.  Make stopping extattrs always succesful to facilitate
always being able to free resources.

927229e57b quotaoff: ignore clean vnodes. Fixes PR kern/37818. 2008-01-24 22:55:21 +00:00
ad
703069c0e9 specfs changes for PR kern/37717 (raidclose() is no longer called on 
shutdown). There are still problems with device access and a PR will be
filed.

- Kill checkalias(). Allow multiple vnodes to reference a single device.

- Don't play dangerous tricks with block vnodes to ensure that only one
  vnode can describe a block device. Instead, prohibit concurrent opens of
  block devices. As a bonus remove the unreliable code that prevents
  multiple file system mounts on the same device. It's no longer needed.

- Track opens by vnode and by device. Issue cdev_close() when the last open
  goes away, instead of abusing vnode::v_usecount to tell if the device is
  open.

7e2790cf6f Convert all the system call entry points from: 
int foo(struct lwp *l, void *v, register_t *retval)
to:
    int foo(struct lwp *l, const struct foo_args *uap, register_t *retval)
Fixup compat code to not write into 'uap' and (in some cases) to actually
pass a correctly formatted 'uap' structure with the right name to the
next routine.
A few 'compat' routines that just call standard ones have been deleted.
All the 'compat' code compiles (along with the kernels required to test
build it).
98% done by automated scripts.

d556dc98b0 Fscow_run(): add a flag "bool data_valid" to note still valid data. 
Buffers run through copy-on-write are marked B_COWDONE.  This condition
is valid until the buffer has run through bwrite() and gets cleared from
biodone().

Welcome to 4.99.39.

61e8303e9d Remove the "struct lwp *" argument from all VFS and VOP interfaces. 
The general trend is to remove it from all kernel interfaces and
this is a start.  In case the calling lwp is desired, curlwp should
be used.

9c31b45f5e Change the fs_clean member of the ffs superblock to be unsigned 
(uint8_t instead of int8_t) - this prevents an ugly sign-extension
printing bug as well as formally undefined behavior when you mount an
unclean fs enough times.

From (my own) PR kern/28134; I've been carrying this patch for three
years, long enough to forget about it, and it's had no ill effects in
that time.

75bdfc0dac Avoid doing bawrite to initialize inode block while holding cylinder 
group block buffer busy.  If filesystem has any active snapshots, bawrite
can come back trying to allocate new snapshot data block from the same
cylinder group and cause deadlock.
