2013-02-20	libceph: drop return value from page vector copy routines	Alex Elder	1	-8/+6
	The return values provided for ceph_copy_to_page_vector() and ceph_copy_from_page_vector() serve no purpose, so get rid of them. Signed-off-by: Alex Elder <elder@inktank.com> Reviewed-by: Josh Durgin <josh.durgin@inktank.com>
2013-02-20	libceph: use void pointers in page vector functions	Alex Elder	1	-5/+5
	The functions used for working with ceph page vectors are defined with char pointers, but they're really intended to operate on untyped data. Change the types of these function parameters to (void *) to reflect this. (Note that the functions now assume void pointer arithmetic works like arithmetic on char pointers.)

2011-03-04	libceph: fix handling of short returns from get_user_pages	Sage Weil	1	-5/+13
	get_user_pages() can return fewer pages than we ask for. We were returning a bogus pointer/error code in that case. Instead, loop until we get all the pages we want or get an error we can return to the caller. Signed-off-by: Sage Weil <sage@newdream.net>
2010-12-17	ceph: handle partial result from get_user_pages	Henry C Chang	1	-2/+2
	The get_user_pages() helper can return fewer than the requested pages. Error out in that case, and clean up the partial result. Signed-off-by: Henry C Chang <henry_c_chang@tcloudcomputing.com> Signed-off-by: Sage Weil <sage@newdream.net>
2010-12-17	ceph: mark user pages dirty on direct-io reads	Henry C Chang	1	-4/+7
	For read operation, we have to set the argument _write_ of get_user_pages to 1 since we will write data to pages. Also, we need to SetPageDirty before releasing these pages. Signed-off-by: Henry C Chang <henry_c_chang@tcloudcomputing.com> Signed-off-by: Sage Weil <sage@newdream.net>
2010-11-09	ceph: fix comment, remove extraneous args	Sage Weil	1	-2/+1
	The offset/length arguments aren't used. Signed-off-by: Sage Weil <sage@newdream.net>
2010-10-21	ceph: factor out libceph from Ceph file system	Yehuda Sadeh	1	-0/+223
	This factors out protocol and low-level storage parts of ceph into a separate libceph module living in net/ceph and include/linux/ceph. This is mostly a matter of moving files around. However, a few key pieces of the interface change as well: - ceph_client becomes ceph_fs_client and ceph_client, where the latter captures the mon and osd clients, and the fs_client gets the mds client and file system specific pieces. - Mount option parsing and debugfs setup is correspondingly broken into two pieces. - The mon client gets a generic handler callback for otherwise unknown messages (mds map, in this case). - The basic supported/required feature bits can be expanded (and are by ceph_fs_client). No functional change, aside from some subtle error handling cases that got cleaned up in the refactoring process. Signed-off-by: Sage Weil <sage@newdream.net>
