Hi Al, After merging the vfs tree, today's linux-next build (arm multi_v7_defconfig) failed like this: fs/ext4/indirect.c: In function 'ext4_ind_direct_IO': fs/ext4/indirect.c:653:2: error: implicit declaration of function 'iov_iter_count' [-Werror=implicit-function-declaration] size_t count = iov_iter_count(iter); ^ Caused by commit 3737c63e1fb0 ("fs: move struct kiocb to fs.h"). aio.h used to include uio.h ... I wonder if there is more fallout from this include file diet. It would have been nice if the more general changes to aio.h were in a separate patch. I added the following patch for today: From: Stephen Rothwell Date: Fri, 13 Mar 2015 11:56:46 +1100 Subject: [PATCH] ext4: iov_iter_count needs linux/uio.h Fixes: 3737c63e1fb0 ("fs: move struct kiocb to fs.h") Signed-off-by: Stephen Rothwell --- fs/ext4/indirect.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/fs/ext4/indirect.c b/fs/ext4/indirect.c index 33308738a06a..a9369e5d2cc1 100644 --- a/fs/ext4/indirect.c +++ b/fs/ext4/indirect.c @@ -20,6 +20,8 @@ * (sct@redhat.com), 1993, 1998 */ +#include + #include "ext4_jbd2.h" #include "truncate.h" -- 2.1.4 -- Cheers, Stephen Rothwell sfr@canb.auug.org.au
