Subject: Re: [PATCHv4 5/6] ext4: Move ext4_fiemap to use iomap framework.

Hi Ritesh,

I love your patch! Perhaps something to improve:

[auto build test WARNING on ext4/dev]
[also build test WARNING on linus/master v5.6-rc3 next-20200227]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see]

base: dev
        # apt-get install sparse
        # sparse version: v0.6.1-173-ge0787745-dirty
        make ARCH=x86_64 allmodconfig
        make C=1 CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__'

If you fix the issue, kindly add following tag
Reported-by: kbuild test robot <>

sparse warnings: (new ones prefixed by >>)

>> fs/ext4/extents.c:4918:24: sparse: sparse: symbol 'ext4_iomap_xattr_ops' was not declared. Should it be static?

Please review and possibly fold the followup patch.
