libceph: expose client options through debugfs

Add a client_options attribute for showing libceph options. Signed-off-by: Ilya Dryomov

libceph, ceph: split ceph_show_options()

2015-04-20T15:55:38Z

Split ceph_show_options() into two pieces and move the piece responsible for printing client (libceph) options into net/ceph. This way people adding a libceph option wouldn't have to remember to update code in fs/ceph. Signed-off-by: Ilya Dryomov

libceph: tcp_nodelay support

2015-02-19T10:31:40Z

TCP_NODELAY socket option set on connection sockets, disables Nagle’s algorithm and improves latency characteristics. tcp_nodelay(default)/notcp_nodelay option flags provided to enable/disable setting the socket option.

libceph: nuke ceph_kvfree()

2014-12-17T17:09:50Z

Use kvfree() from linux/mm.h instead, which is identical. Also fix the ceph_buffer comment: we will allocate with kmalloc() up to 32k - the value of PAGE_ALLOC_COSTLY_ORDER, but that really is just an implementation detail so don't mention it at all. Signed-off-by: Ilya Dryomov

libceph: remove redundant declaration

libceph: add ceph_kv{malloc,free}() and switch to them

2014-01-26T10:34:23Z

Encapsulate kmalloc vs vmalloc memory allocation and freeing logic into two helpers, ceph_kvmalloc() and ceph_kvfree(), and switch to them. ceph_kvmalloc() kmalloc()'s a maximum of 8 pages, anything bigger is vmalloc()'ed with __GFP_HIGHMEM set. This changes the existing behaviour: - for buffers (ceph_buffer_new()), from trying to kmalloc() everything and using vmalloc() just as a fallback - for messages (ceph_msg_new()), from going to vmalloc() for anything bigger than a page - for messages (ceph_msg_new()), from disallowing vmalloc() to use high memory Signed-off-by: Ilya Dryomov Reviewed-by: Sage Weil

libceph: all features fields must be u64

2013-12-31T18:32:08Z

In preparation for ceph_features.h update, change all features fields from unsigned int/u32 to u64. (ceph.git has ~40 feature bits at this point.) Signed-off-by: Ilya Dryomov Reviewed-by: Sage Weil

libceph: create source file "net/ceph/snapshot.c"

2013-05-02T04:20:08Z

This creates a new source file "net/ceph/snapshot.c" to contain utility routines related to ceph snapshot contexts. The main motivation was to define ceph_create_snap_context() as a common way to create these structures, but I've moved the definitions of ceph_get_snap_context() and ceph_put_snap_context() there too. (The benefit of inlining those is very small, and I'd rather keep this collection of functions together.) Signed-off-by: Alex Elder Reviewed-by: Josh Durgin
