Subject: [patch 137/192] mm: vmalloc: add cond_resched() in __vunmap()
Date: Mon, 28 Jun 2021 19:40:27 -0700 [thread overview]

Subject: mm: vmalloc: add cond_resched() in __vunmap()
On non-preemptible kernel builds the watchdog can complain about soft
lockups when vfree() is called against large vmalloc areas:
[ 210.851798] kvmalloc-test: vmalloc(2199023255552) succeeded

Like in other range zapping routines that iterate over a large list, lets
just add cond_resched() within __vunmap()'s page-releasing loop in order
to avoid the watchdog splats.
