Subject[PATCH v06 24/36] uapi linux/coda_psdev.h: move upc_req definition from uapi to kernel side headers
Date
Only users of upc_req in kernel side fs/coda/psdev.c and fs/coda/upcall.c
already include linux/coda_psdev.h.

Suggested by Jan Harkes <jaharkes@cs.cmu.edu> on lkml message
<20150531111913.GA23377@cs.cmu.edu>.

Fixes these include/uapi/linux/coda_psdev.h compilation errors in userspace:

./linux/coda_psdev.h:12:19: error: field ‘uc_chain’ has incomplete type
struct list_head uc_chain;
^
./linux/coda_psdev.h:13:2: error: unknown type name ‘caddr_t’
caddr_t uc_data;
^
./linux/coda_psdev.h:14:2: error: unknown type name ‘u_short’
u_short uc_flags;
^
./linux/coda_psdev.h:15:2: error: unknown type name ‘u_short’
u_short uc_inSize; /* Size is at most 5000 bytes */
^
./linux/coda_psdev.h:16:2: error: unknown type name ‘u_short’
u_short uc_outSize;
^
./linux/coda_psdev.h:17:2: error: unknown type name ‘u_short’
u_short uc_opcode; /* copied from data to save lookup */
^
./linux/coda_psdev.h:19:2: error: unknown type name ‘wait_queue_head_t’
wait_queue_head_t uc_sleep; /* process' wait queue */
^
