Description
After one complete iteration of the BSC_Tests TTCN-3 testsuite, we have a number of stale bsc_subscr entries that should have been cleaned up:
struct llist_head contains 592 bytes in 13 blocks (ref 0) 0x84a5e80
struct bsc_subscr contains 48 bytes in 1 blocks (ref 0) 0x94e59b0

After applying https://gerrit.osmocom.org/5554 to get the "show subscriber all" comand,
I get the following output:
OsmoBSC> show subscriber all IMSI TMSI LAC Use 001010123456789 ffffffff 65534 3 001010100000001 a1b2c301 65534 1 001010100000002 a1b2c302 65534 1 001010100000003 a1b2c303 65534 1 001010000000004 a1b2c304 65534 1 001010000000005 a1b2c305 65534 1 001010000000006 ffffffff 65534 1 001010000000007 ffffffff 65534 1 001010000000008 ffffffff 65534 1 001010000000009 ffffffff 65534 1 001010000000010 ffffffff 1 1 001010000000011 ffffffff 65534 1
It seems they are directly related to the paging tests. We must have a ref count leak in there.
