Subject: [V2 PATCH 00/62] highmem: remove the second argument of kmap_atomic/kunmap_atomic
V1: https://lkml.org/lkml/2011/1/30/13
V1->V2: Split patches and rebase them to the latest linus tree.
Now the second argument of kmap_atomic()/kunmap_atomic() is totally
unused, this patchset removes it from all callers.
But for backward compatibility, we still keep the deprecated form,
and will warn the users if they still use the deprecated one, like this:
drivers/block/drbd/drbd_bitmap.c: In function ‘bm_page_io_async’:
drivers/block/drbd/drbd_bitmap.c:973:3: warning: ‘kmap_atomic_deprecated’ is deprecated (declared at /home/wangcong/linux-2.6/include/linux/highmem.h:124)
drivers/block/drbd/drbd_bitmap.c:977:3: warning: ‘kunmap_atomic_deprecated’ is deprecated (declared at /home/wangcong/linux-2.6/include/linux/highmem.h:144)
To schedule the final removal of these stuffs, I also write some doc into
feature-removal-schedule.txt, see the last patch in this thread.
Most of this patch is generated by the following commands:
find . -name '*.[c|h]' -exec sed -i -e 's#\bkmap_atomic(\(.*\),.*)#kmap_atomic(\1)#' '{}' \;
find . -name '*.[c|h]' -exec sed -i -e 's#\bkunmap_atomic(\(.*\),.*)#kunmap_atomic(\1)#' '{}' \;
the rest exceptions are fixed by hands.
This patch passes 'make allyesconfig' test on both ppc64 and x86_64.
BTW, all patches can be found on my github:
git@...hub.com:congwang/linux.git #for-next
and the final removal patches can be found here:
git@...hub.com:congwang/linux.git #for-3.5
