libceph: convert ceph_snap_context.nref from atomic_t to refcount_t

2017-05-04T07:19:18+00:00

refcount_t type and corresponding API should be used instead of atomic_t when the variable is used as a reference counter. This allows to avoid accidental refcounter overflows that might lead to use-after-free situations.

libceph: remove unneeded stddef.h include

2017-02-20T11:16:10+00:00

This was causing a build failure for openrisc when using musl and gcc 5.4.0 since the file is not available in the toolchain. It doesnt seem this is needed and removing it does not cause any build warnings for me. Signed-off-by: Stafford Horne Signed-off-by: Ilya Dryomov

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

2013-05-02T04:20:08+00:00

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
