- Not enabled by default. Needs kernel option FFS_SNAPSHOT.
- Change parameters of ffs_blkfree.
- Let the copy-on-write functions return an error so spec_strategy
may fail if the copy-on-write fails.
- Change genfs_*lock*() to use vp->v_vnlock instead of &vp->v_lock.
- Add flag B_METAONLY to VOP_BALLOC to return indirect block buffer.
- Add a function ffs_checkfreefile needed for snapshot creation.
- Add special handling of snapshot files:
Snapshots may not be opened for writing and the attributes are read-only.
Use the mtime as the time this snapshot was taken.
Deny mtime updates for snapshot files.
- Add function transferlockers to transfer any waiting processes from
one lock to another.
- Add vfsop VFS_SNAPSHOT to take a snapshot and make it accessible through
a vnode.
- Add snapshot support to ls, fsck_ffs and dump.
Welcome to 2.0F.

an _LKM.
This adds pools to the list of things that lkms must do manually
because they're set up with link sets. Not that there's anything
wrong with link sets, but that we need to try harder to remember that
lkms are second class citizens. Of a sort.
no longer use and/or need it
- removed casts from unionfs, deadfs and fdesc
(there are more to hunt down still)
- changed vfs_quotactl args argumet from caddr_t to void *
- changed vfs_quotactl structures/callers to reflect the api change
Compiled fine and ran for about a day. Approved/reviewed by
christos@netbsd.org and gimpy@netbsd.org.
to pool_init. Untouched pools are ones that either in arch-specific
code, or aren't initialiased during initial system startup.
Convert struct session, ucred and lockf to pools.
Gone are the old kern_sysctl(), cpu_sysctl(), hw_sysctl(),
vfs_sysctl(), etc, routines, along with sysctl_int() et al. Now all
nodes are registered with the tree, and nodes can be added (or
removed) easily, and I/O to and from the tree is handled generically.
Since the nodes are registered with the tree, the mapping from name to
number (and back again) can now be discovered, instead of having to be
hard coded. Adding new nodes to the tree is likewise much simpler --
the new infrastructure handles almost all the work for simple types,
and just about anything else can be done with a small helper function.
All existing nodes are where they were before (numerically speaking),
so all existing consumers of sysctl information should notice no
difference.
PS - I'm sorry, but there's a distinct lack of documentation at the
moment. I'm working on sysctl(3/8/9) right now, and I promise to
watch out for buses.
* Remove the "lwp *" argument that was added to vget(). Turns out
that nothing actually used it!
* Remove the "lwp *" arguments that were added to VFS_ROOT(), VFS_VGET(),
and VFS_FHTOVP(); all they did was pass it to vget() (which, as noted
above, didn't use it).
* Remove all of the "lwp *" arguments to internal functions that were added
just to appease the above.
be inserted into ktrace records. The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.
Bump the kernel rev up to 1.6V
- Under chroot it displays only the visible filesystems with appropriate paths.
- The statfs f_mntonname gets adjusted to contain the real path from root.
- While was there, fixed a bug in ext2fs, locking problems with vfs_getfsstat(),
and factored out some of the vfsop statfs() code to copy_statfs_info(). This
fixes the problem where some filesystems forgot to set fsid.
- Made coda look more like a normal fs.
This is potentially fragile, since the vnode may have been reclaimed
in vflush(), and used by different filesystem. This wouldn't actually
happen due to n_parent link to parent directory, but better safe
than sorry.
Since sm_root is only and strictly cache to speed up VFS_ROOT(),
it can be acquired/dropped any time. Rearrange code to not
require sm_root set, and change smbfs_root() back to set
sm_root if it's not set yet. smbfs_unmount() now only vrele()s
the root vnode if sm_root is set, and doesn't try reacquire it
if vflush() fails.
problem with vref() after vflush() pointed out by Bill Studenmund
smbfs_setroot()
remove pointless if() and MNT_LOCAL flag handling in smbfs_unmount()
turn the check for non-null sm_root to KASSERT() in smbfs_statfs()
adjust some comments
* lock/unlock mntvnode_slock and vnode interlock appropriately
* use LK_NOWAIT for vget()
* adjust the check for vnode being dirty to check fs-private 'modified' flag,
and drop waitfor/VOP_ISLOCKED() check
* g/c unused members 'mount_point', 'root_path', which only take space
* rename 'dev' to 'dev_fd' to more closely match what it is
* add 'export' member to avoid changing this again if ever smbfs would
be made exportable
bump SMBFS_VERMIN - ABI/API change; mount_smbfs needs to be recompiled
to work again
so that the filesystem wouldn't appear as busy when it's not, and vref()
it back if the vflush() fails
LK_DRAIN sm_hashlock before freeing the smbmount struct
g/c one meaningless check in smbfs_root()
* g/c superfluous printfs
* use vcp on one more place
* don't need to check result of allocation with M_WAITOK
* just exlicitly return (0) on the success path, rather than return (error)
terminate the check if options SMB was included
remove the #ifndef FB_CURRENT around f_mntonname; FB_CURRENT used to be defined
in netsmb headers, and this caused f_mntonname to not be initialized
terminate the messy code setting f_mntfromname, and use snprintf() instead
malloc types into a structure, a pointer to which is passed around,
instead of an int constant. Allow the limit to be adjusted when the
malloc type is defined, or with a function call, as suggested by
Jonathan Stone.
