[LU-14138] Move more members in PTLRPC request into pill

• Type: Improvement
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.15.0
• Assignee: Qian Yingjin
• Reporter: Qian Yingjin

Description

Many fields in data struct @ptlrpc_request can be moved into the data struct @req_capsule:
/** Request message - what client sent */
struct lustre_msg *rq_reqmsg;
/** Reply message - server response */
struct lustre_msg *rq_repmsg;
/** Fields that help to see if request and reply were swabbed or not */
__u32 rq_req_swab_mask;
__u32 rq_rep_swab_mask;

After this data structure reconstructing, req_capsule can be more common usage and it makes pack and unpack sub request for the coming batch metadata processing more easily.
