[PATCH V9 20/33] fs: add read_iter and write_iter to several file systems
From: Dave Kleikamp
Date: Wed Oct 16 2013 - 10:14:49 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, adfs, affs, bfs, exofs, ext2,
ext3, fat, f2fs, hfs, hfsplus, hostfs, hpfs, jfs, jffs2, logfs, minix, nilfs2,
omfs, ramfs, reiserfs, romfs, sysv, and ufs.
