Subject: Re: [PATCH v5 4/8] x86/mm/tlb: Flush remote and local TLBs concurrently
Date: Thu, 18 Feb 2021 08:14:08 +0000 [thread overview]
Message-ID: <20210218081408.GB335524@infradead.org> (raw)
In-Reply-To: <20210209221653.614098-5-namit@vmware.com>
Given that the last patch killed the last previously existing
user of on_each_cpu_cond_mask there are now the only users.

Which means the cond_func is unused, and thus on_each_cpu_cond_mask can
go away entirely in favor of on_each_cpu_cond.
