scsi: use __u{8,16,32,64} instead of uint{8,16,32,64}_t in uapi headers
When CONFIG_UAPI_HEADER_TEST=y, exported headers are compile-tested to make sure they can be included from user-space. Currently, scsi_bsg_fc.h, scsi_netlink.h, and scsi_netlink_fc.h are excluded from the test coverage. To make them join the compile-test, we need to fix the build errors attached below. For a case like this, we decided to use __u{8,16,32,64} variable types in this discussion: https://lkml.org/lkml/2019/6/5/18 Build log: CC usr/include/scsi/scsi_netlink_fc.h.s CC usr/include/scsi/scsi_netlink.h.s CC usr/include/scsi/scsi_bsg_fc.h.s In file included from ./usr/include/scsi/scsi_netlink_fc.h:10:0, from <command-line>:32: ./usr/include/scsi/scsi_netlink.h:29:2: error: unknown type name uint8_t uint8_t version; ^~~~~~~ ./usr/include/scsi/scsi_netlink.h:30:2: error: unknown type name uint8_t uint8_t transport; ^~~~~~~ ./usr/include/scsi/scsi_netlink.h:31:2: error: unknown type name uint16_t uint16_t magic; ^~~~~~~~ ./usr/include/scsi/scsi_netlink.h:32:2: error: unknown type name uint16_t uint16_t msgtype; ^~~~~~~~ CC usr/include/rdma/vmw_pvrdma-abi.h.s ./usr/include/scsi/scsi_netlink.h:33:2: error: unknown type name uint16_t uint16_t msglen; ^~~~~~~~ ./usr/include/scsi/scsi_netlink.h:34:33: error: uint64_t undeclared here (not in a function); did you mean __uint128_t ? } __attribute__((aligned(sizeof(uint64_t)))); ^~~~~~~~ __uint128_t ./usr/include/scsi/scsi_netlink.h:78:2: error: expected specifier-qualifier-list before uint64_t uint64_t vendor_id; ^~~~~~~~ In file included from <command-line>:32:0: ./usr/include/scsi/scsi_netlink_fc.h:46:2: error: expected specifier-qualifier-list before uint64_t uint64_t seconds; ^~~~~~~~ make[2]: *** [scripts/Makefile.build;302: usr/include/scsi/scsi_netlink_fc.h.s] Error 1 make[2]: *** Waiting for unfinished jobs....
