From 020f6fd093b628af5a34eb1cea9a3d800aa17ffb Mon Sep 17 00:00:00 2001 From: Alexander Motin Date: Tue, 7 Nov 2023 14:37:18 -0500 Subject: [PATCH] FreeBSD: Implement taskq_init_ent() Previously taskq_init_ent() was an empty macro, while actual init was done by taskq_dispatch_ent(). It could be slightly faster in case taskq never enqueued. But without it taskq_empty_ent() relied on the structure being zeroed by somebody else, that is not good. As a side effect this allows the same task to be queued several times, that is normal on FreeBSD, that may or may not get useful here also one day.
