# 1.29 05-Oct-2018 uwe

Minor markup fixes. Add a missing word.


# 1.28 05-Oct-2018 wiz

Simplify macro usage. No visible change.


# 1.27 05-Oct-2018 hannken

Bring back three state file system suspension:

NORMAL -> SUSPENDING -> SUSPENDED

and add operation fstrans_start_lazy() that only blocks while SUSPENDED.

Change vndthread() support operation handle_with_rdwr() to bracket
its file system operations by fstrans_start_lazy() and fstrans_done().

Remove workaround for ancient HTML generation code.


# 1.25 04-Jun-2017 hannken

Operations fstrans_start() and fstrans_start_nowait() now always
use FSTRANS_SHARED as lock type so remove the lock type argument.

File system state FSTRANS_SUSPENDING is now unused so remove it.

Regen vnode_if files.

- Explain intent, not just mechanism.
- Add internal cross-references and redundant information from
different callers' perspectives.

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.

# 1.10 08-Oct-2007 hannken

Bump date.


# 1.9 07-Oct-2007 hannken

Update the file system copy-on-write handler.

- Instead of hooking the handler on the specdev of a mounted file system
hook directly on the `struct mount'.

- Rename from `vn_cow_*' to `fscow_*' and move to `kern/vfs_trans.c'. Use
`mount_*specific' instead of clobbering `struct mount' or `struct specinfo'.

- Replace the hand-made reader/writer lock with a krwlock.

- Keep `vn_cow_*' functions and mark as obsolete.

- Welcome to NetBSD 4.99.32 - `struct specinfo' changed size.
