[PATCH] generic_file_buffered_write fixes
Anton Altaparmakov <aia21@cam.ac.uk> points out:
- It calls fault_in_pages_readable() which is completely bogus if @nr_segs >
1. It needs to be replaced by a to be written
"fault_in_pages_readable_iovec()".
- It increments @buf even in the iovec case thus @buf can point to random
memory really quickly (in the iovec case) and then it calls
fault_in_pages_readable() on this random memory.
