Subject: Re: [PATCH/RFC] mm: add and use batched version of __tlb_remove_table()
Date: Fri, 17 Dec 2021 19:39:36 +0100 [thread overview]
Message-ID: <YbzZaFY+ht+bUtcz@ravnborg.org> (raw)

Hi Nikita,
How about adding the following to tlb.h:
#ifndef __tlb_remove_tables
static void __tlb_remove_tables(...)
{
....
}
#endif
And then the few archs that want to override __tlb_remove_tables
needs to do a
#define __tlb_remove_tables __tlb_remove_tables
static void __tlb_remove_tables(...)
{
...
}
In this way the archs that uses the default implementation needs not do
anything.
A few functions already uses this pattern in tlb.h - see for example tlb_start_vma
io.h is another file where you can see the same pattern.
Sam
