[PATCH 17/22] fs: add read_iter and write_iter to several file systems
From: Dave Kleikamp
Date: Mon Oct 22 2012 - 11:17:16 EST
These are the simple ones.
File systems that use generic_file_aio_read() and generic_file_aio_write()
can trivially support generic_file_read_iter() and generic_file_write_iter().
This patch adds those file_operations for 9p, ext2, ext3, fat, hfs, hfsplus,
jfs, nilfs2, and reiserfs.
