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: 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

libceph: define CEPH_MSG_MAX_MIDDLE_LEN

This is probably unnecessary but the code read as if it were wrong in read_partial_message(). Signed-off-by: Alex Elder Reviewed-by: Josh Durgin

libceph: drop return value from page vector copy routines

2013-02-20T01:14:05Z

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 Reviewed-by: Josh Durgin

libceph: use void pointers in page vector functions

2013-02-20T01:14:04Z

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.)
