linux-next: build warning after merge of the cifs tree

linux-next: build warning after merge of the cifs tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 584 bytes --]

Hi all,

After merging the cifs tree, today's linux-next build (powerpc
ppc64_defconfig) produced this warning:

fs/cifs/file.c: In function 'cifs_iovec_write':
fs/cifs/file.c:1740: warning: passing argument 6 of 'CIFSSMBWrite2' from incompatible pointer type
fs/cifs/cifsproto.h:343: note: expected 'unsigned int *' but argument is of type 'size_t *'

Introduced by commit 72432ffcf555decbbae47f1be338e1d2f210aa69 ("CIFS:
Implement cifs_strict_writev (try #4)").

The following patch should silence that warning.

Subject: [PATCH] cifs: fix compiler warning about incompatible pointer type

fs/cifs/file.c: In function ‘cifs_iovec_write’:
fs/cifs/file.c:1740:9: warning: passing argument 6 of ‘CIFSSMBWrite2’ from incompatible pointer type

I've just noriced another bug: that 'i' variable should be unsigned
long. I will recreate the patch with this fix.

I fixed this a few days ago along with a number of other compiler
warnings in:

    [PATCH] cifs: clean up some compiler warnings

...just waiting for Steve to merge it.
