Subject: [PATCH v1 0/3] mm/gup: consistently call it GUP-fast
Date: Tue,  2 Apr 2024 14:55:13 +0200	[thread overview]
Message-ID: <20240402125516.223131-1-david@redhat.com> (raw)

Some cleanups around function names, comments and the config option of
"GUP-fast" -- GUP without "lock" safety belts on.

With this cleanup it's easy to judge which functions are GUP-fast specific.
We now consistently call it "GUP-fast", avoiding mixing it with "fast GUP",
"lockless", or simply "gup" (which I always considered confusing in the
ode).

So the magic now happens in functions that contain "gup_fast", whereby
gup_fast() is the entry point into that magic. Comments consistently
reference either "GUP-fast" or "gup_fast()".

Based on mm-unstable from today. I won't CC arch maintainers, but only
arch mailing lists, to reduce noise.

Tested on x86_64, cross compiled on a bunch of archs.

RFC -> v1:
* Rebased on latest mm/mm-unstable
* "mm/gup: consistently name GUP-fast functions"
 -> "internal_get_user_pages_fast()" -> "gup_fast_fallback()"
 -> "undo_dev_pagemap()" -> "gup_fast_undo_dev_pagemap()"
 -> Fixup a bunch more comments
* "mm/treewide: rename CONFIG_HAVE_FAST_GUP to CONFIG_HAVE_GUP_FAST"
 -> Take care of RISCV
