Hi Stephen,
Can you please take this series into the next tree? It has been already
in next-tree for 5.14:
https://lore.kernel.org/linux-mmc/YSeduU41Ef568xhS@alley/T/
But it was damaged and we decided to merge it in 5.15 cycle. No changes
comparing to 5.14, except for Andy's patch that was already upstreamed
and therefore removed from here.
The git tree is here:
https://github.com/norov/linux/tree/bitmap-20210929
Thanks,
Yury

find_first_bit() and find_first_zero_bit() are not protected with
ifdefs as other functions in find.h. It causes build errors on some
platforms if CONFIG_GENERIC_FIND_FIRST_BIT is enabled.

Fixes: 2cc7b6a44ac2 ("lib: add fast path for find_first_*_bit() and find_last_bit()")

It's convenient to have all find_bit declarations in one place.

This is a dup with the same subject. Which one should we look into?

Please ignore this (short) series. It's a duplication, my connection
was broken and I had to restart submitting.

There is no big hurry, the next linux-next release will not be until
Tuesday (my time). So you have time to retest after the rebase.

Thanks.
I also need a branch name that will stay the same. I will fetch that
branch every day and use whatever you have set that branch to.
Here are the rules for inclusion in linux-next:
You will need to ensure that the commits in your tree/branch have
been:
* submitted under GPL v2 (or later) and include the Contributor's
Signed-off-by,
* posted to the relevant mailing list,
* reviewed by you (or another maintainer of your subsystem tree),
* successfully unit tested, and
* destined for the current or next Linux merge window.
Basically, this should be just what you would send to Linus (or ask him
to fetch). It is allowed to be rebased if you deem it necessary.

Ok, I'll resend it based on Linus tree shortly

Sorry, I cannot include that in linux-next since it it based on (an old
version of) linux-next itself. If it needs to be based on other trees in
linux-next, then it has to be added to Andrew Morton's patch series (in
the post linux-next section. Otherwise, if it can be based on Linus
Torvald's tree (even with a few conflicts), then that is better.

Hi Stephen,
Can you please take this series into the next tree? It has been already
in next-tree for 5.14:
https://lore.kernel.org/linux-mmc/YSeduU41Ef568xhS@alley/T/
But it was damaged and we decided to merge it in 5.15 cycle. No changes
comparing to 5.14, except for Andy's patch that was already upstreamed
and therefore removed from here.
The git tree is here:
https://github.com/norov/linux/tree/bitmap-20210929
Thanks,
Yury
