We've got no modular users left, and any potential modular user is better
of with iov_iter based variants.

No modular users left.  Given that they take user pointers there is no
good reason to export it to drivers to start with.

No modular users left, and any new ones should use kernel_read/write
or iov_iter variants instead.

fs: make the buf argument to __kernel_write a void pointer

2017-09-04T23:05:15+00:00

This matches kernel_read and kernel_write and avoids any need for casts in
the callers.

2017-09-04T23:05:15+00:00

Make the position an in/out argument like all the other read/write
helpers and and make the buf argument a void pointer.

Use proper ssize_t and size_t types for the return value and count
argument, move the offset last and make it an in/out argument like
all other read/write helpers, and make the buf argument a void pointer
to get rid of lots of casts in the callers.
