Subject: tdb2: allow multiple opens of the same file.
X-Git-Url: http://git.ozlabs.org/?p=ccan;a=commitdiff_plain;h=bb4d59ee1e914df9f8066e59a9c9a6604e581c40;hp=bb4d59ee1e914df9f8066e59a9c9a6604e581c40

tdb2: allow multiple opens of the same file.

Finally, we enable sharing of the struct tdb_file.  We add a reference count
so we can free the struct tdb_file when the last tdb is closed.
