[RFC] free_pages stuff
From: Al Viro
Date: Mon Dec 21 2015 - 18:46:25 EST
FWIW, I'd done a proof-of-concept patch series converting the things
to
* free_page() and free_pages() taking the address to free as a pointer
* get_zeroed_page() returning a pointer
* get_free_page()/get_free_pages() added, both returning a pointer
* __get_dma_pages() replaced with get_dma_page() (again, returns
a pointer)
Result is in
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git work.pages
The first 3 commits in there are flagday ones; doing them from scratch took
about 4 hours total. The rest isn't system-wide (well, after introduction
of get_free_page() there's a bulk replacement of
something *p = (something *)__get_free_page(...);
with
something *p = get_free_page(...);
but all chunks of that are independent - it can be split by subsystem,
etc.) and would go into individual subsystem trees at leisure.
83 commits so far, 568 files changed, 1956 insertions(+), 2202 deletions(-)
Total: 70 casts added, 1408 removed. All __get_free_page() calls in the
tree converted; a few __get_free_pages() ones remain (6, AFAICS).
This was mostly a proof-of-concept thing - fixes for bogosities caught in
process will, of course, be cherry-picked and sent to relevant trees,
but the main goal was to find out how much boilerplating is there due to
signatures of free_page, __get_free_page and friends (see above - more than
a thousand casts, with usual effect on safety, etc.) and how painful would the
series be (several hours to do the flagday part from scratch, not particularly
hard to do followup cleanups; most of those cleanups will be trivial to rebase)
IMO the results look interesting. It's obviously too late in this cycle
(and I used the mainline circa last Thursday as the starting point), but
I could redo the flagday ones easily at any point - for example, overnight
after -rc1. I'm not sure what's the best merge strategy here - I could put
these 3 into a never-rebased branch, include it into for-next and ask the
folks to pull it into their trees before adding followups. Alternatively,
we could put these 3 into mainline right after -rc1 (or even into it, if you
give me several hours of warning along the lines of "I'm done merging subtrees
into -rc1 now").
In any case, decision whether to do that thing at all belongs to you - it's
a flagday change in several functions used all over the tree and whichever
way we do it, I need an explicit ACK from you on the change in principle.
If you consider that change too disruptive, please say so. I'm not asking
to ACK the specific patch series, just the possibility of this API change.
Please, take a look at that branch and comment. I've taken that about as
far as I can without an ACK or NAK from you...
