Subject: tdb: add "freelist_size" sub-command to tdbtool
X-Git-Url: http://git.samba.org/?p=metze%2Fsamba%2Fwip.git;a=commitdiff_plain;h=6502df58391cc8d3477d1c5cce4a6aa027d439bd

tdb: add "freelist_size" sub-command to tdbtool

With the new code, this has the side effect of
merging adjacent records in the freelist if the
database is not read-only.
