# commit 3e60b11
# BUG/MEDIUM: stick-tables: Decrement ref_cnt in table_* converters
#
# When using table_* converters ref_cnt was incremented
# and never decremented causing entries to not expire.
#
# The root cause appears to be that stktable_lookup_key()
# was called within all sample_conv_table_* functions which was
# incrementing ref_cnt and not decrementing after completion.
#
# Added stktable_release() to the end of each sample_conv_table_*
# function and reworked the end logic to ensure that ref_cnt is
# always decremented after use.
#
# This should be backported to 1.8
