2010-02-10ceph: buffer decoding helpersSage Weil
Helper for decoding into a ceph_buffer, and other misc decoding helpers we will need. Signed-off-by: Yehuda Sadeh <yehuda@hq.newdream.net> Signed-off-by: Sage Weil <sage@newdream.net>
2009-12-07ceph: simplify ceph_buffer interfaceSage Weil
We never allocate the ceph_buffer and buffer separtely, so use a single constructor. Disallow put on NULL buffer; make the caller check. Signed-off-by: Sage Weil <sage@newdream.net>
2009-12-07ceph: use kref for ceph_bufferSage Weil

2009-10-06ceph: ref counted bufferSage Weil
struct ceph_buffer is a simple ref-counted buffer. We transparently choose between kmalloc for small buffers and vmalloc for large ones. This is currently used only for allocating memory for xattr data. Signed-off-by: Sage Weil <sage@newdream.net>
