After=20resetting my commit to 0bb2f7a1ad1f, which is before my changes, =
the warning still exists.

The warning originates from test_txmsg_redir_wait_sndmem(), which perform=
s
'KTLS + sockmap with redir EGRESS and limited receive buffer'.

The memory charge/uncharge logic is problematic, I need some time to inve=
stigate and fix it.

Thanks.
