Subject: tdb: use tdb_nest_lock() for transaction lock.
X-Git-Url: http://git.ozlabs.org/?p=ccan;a=commitdiff_plain;h=99e576ac94fd86fcba188fb72ced9e8087ac1680;hp=99e576ac94fd86fcba188fb72ced9e8087ac1680

tdb: use tdb_nest_lock() for transaction lock.

Rather than a boutique lock and a separate nest count, use our
newly-generic nested lock tracking for the transaction lock.

Note that the tdb_have_extra_locks() and tdb_release_extra_locks()
functions have to skip over this lock now it is tracked.
