Use "diffstat -p 1 -w 70" per Documentation/SubmittingPatches.

Use proper kernel-doc notation, per Documentation/kernel-doc-nano-HOWTO.txt.

This comment block should be:

/**
* generic_file_buffered_write - handle an iov
* @iocb: file operations
* @iov: vector of data to write
* @nr_segs: number of iov segments
* @pos: position in the file
* @ppos: position in the file after this function
* @count: number of bytes to write
* @written: offset in iov->base (data to skip on write)
*
* This function will do 3 main tasks for each iov:
* - prepare a write
* - copy the data from iov into a new page
* - commit this page
*/
