Subject[PATCH 34/40] trace syscalls: Convert generic syscalls without long return type
Date
From: Ian Munsie <imunsie@au1.ibm.com>

This patch converts a number of syscalls from the generic code that had
return types other than long to use the new COMPAT_SYSCALL_DEFINEx_RET
macros so their metadata is recorded for tracing.
