*	Linux 4.7 compat: use iterate_shared for concurrent readdir	Chunwei Chen	2016-05-20	1	-14/+35
\| \| \| \| \| \| \| \| \| \| \| \| \|	Register iterate_shared if it exists so the kernel will used shared lock and allowing concurrent readdir. Also, use shared lock when doing llseek with SEEK_DATA or SEEK_HOLE to allow concurrent seeking.

*	Linux 3.11 compat: fops->iterate()	Richard Yao	2013-08-15	1	-0/+43
	Commit torvalds/linux@2233f31aade393641f0eaed43a71110e629bb900 replaced ->readdir() with ->iterate() in struct file_operations. All filesystems must now use the new ->iterate method. To handle this the code was reworked to use the new ->iterate interface. Care was taken to keep the majority of changes confined to the ZPL layer which is already Linux specific. However, minor changes were required to the common zfs_readdir() function. Compatibility with older kernels was accomplished by adding versions of the trivial dir_emit* helper functions. Also the various _readdir() functions were reworked in to wrappers which create a dir_context structure to pass to the new _iterate() functions. Unfortunately, the new dir_emit* functions prevent us from passing a private pointer to the filldir function. The xattr directory code leveraged this ability through zfs_readdir() to generate the list of xattr names. Since we can no longer use zfs_readdir() a simplified zpl_xattr_readdir() function was added to perform the same task.
