*	Fix loop device becomes read-only	Chunwei Chen	2017-03-06	1	-1/+21
\| \| \| \| \| \| \| \| \| \| \| \| \|	Commit 933ec99 removes read and write from f_op because the vfs layer will select iter_write or aio_write automatically. However, for Linux <= 4.0, loop_set_fd will actually check f_op->write and set read-only if not exists. This patch add them back and use the generic do_sync_{read,write} for aio_{read,write} and new_sync_{read,write} for {read,write}_iter.

*	Retire .write/.read file operations	Chunwei Chen	2017-01-27	1	-0/+21
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	The .write/.read file operations callbacks can be retired since support for .read_iter/.write_iter and .aio_read/.aio_write has been added. The vfs_write()/vfs_read() entry functions will select the correct interface for the kernel. This is desirable because all VFS write/read operations now rely on common code. This change also add the generic write checks to make sure that ulimits are enforced correctly on write.

*	Linux 4.1 compat: use read_iter() / write_iter()	Matus Kral	2015-06-18	1	-0/+27
	Linux 3.15 commit torvalds/linux@293bc98 introduced two new methods. The ->read_iter() and ->write_iter() methods were designed to replace the ->aio_read() and ->aio_write() interfaces. Both interfaces were preserved for several kernel releases in order to migrate all existing consumers to the new interfaces. But as of Linux 4.1 the legacy interface has been retired and the ZFS code must be updated to use the new interfaces. Signed-off-by: Brian Behlendorf <[email protected]> Closes #3352
