[sheepdog] [PATCH v4 0/8] redesign a new cache fd pool

[Liu Yuan]

From: Liu Yuan <tailai.ly at taobao.com>

v4:
 - group idx and fd as struct sockfd for sheep_{get,put,del}_sockfd()
 - add a sub-structure for write_info
 - refactor forward_read_obj_req()
 - remove unused headers

v3:
 - fix forward_read_obj_req()

v2:
 - address some coding style problems
 - embed node_id into struct sd_node, sd_vnode
 - remove vnode_node_cmp and node_cmp, use node_id_cmp instead
 - add some more comments

Liu Yuan (8):
  sheep: redesign a new cached sockfd pool
  sheep, sockfd cache: cache more than one FD for each node
  sheep: refactor forward_write_obj_req()
  sheep: output hex for error code
  sheep: try best forward_read_obj_req()
  sheep: embed struct node_id into struct {sd_node, sd_vnode}
  sheep: use node_id_cmp to compare node
