[PATCH] ext4: fix some s64 printing warnings

[Stephen Rothwell]

A powerpc ppc64_defconfig build of Linus' current tree produces these
warnings:

fs/ext4/balloc.c: In function 'ext4_has_free_blocks':
fs/ext4/balloc.c:617: warning: format '%lld' expects type 'long long int', but argument 2 has type 's64'
fs/ext4/inode.c: In function 'ext4_print_free_blocks':
fs/ext4/inode.c:1833: warning: format '%lld' expects type 'long long int', but argument 2 has type 's64'
fs/ext4/inode.c:1835: warning: format '%lld' expects type 'long long int', but argument 2 has type 's64'

Fix them up with the usual casts.

Hi Stephen,

Thanks for submitting the patch!  As it turns out, a patch that was
pretty much identical to yours was submitted by Alexander Beregalov
and was merged into mainline as of 2.6.28-rc5, as commit ID ba8292e2.

Regards,
