[PATCH 5/9] net/mana: reset FD in interrupt handle

Wed Oct 21 11:23:14 CEST 2026


The interrupt handle references the ibverbs async_fd which is owned
by the ibverbs context, not by this driver. Clear the FD reference
before freeing the interrupt handle to avoid a spurious leak warning.

Fixes: d770ee9caed0 ("interrupts: warn on leaked FDs")
