Message-ID: <51085D83.60801@oracle.com>
Date: Tue, 29 Jan 2013 17:38:43 -0600
From: Dave Kleikamp <dave.kleikamp@...cle.com>

Subject: [PATCH V6 18/30] fs: add read_iter and write_iter to several file
systems
[ Reposting with a much shorter cc list as this patch didn't make it to
lkml.]
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.
