perf trace: Beautify new write hint fcntl commands
Those introduced by the commit c75b1d9421f8 ("fs: add fcntl() interface for setting/getting write life time hints"), tested using the proggie in that commit comment:
# perf trace -e fcntl ./write_hint write_hint.c fcntl: F_GET_RW_HINT: Invalid argument 0.000 ( 0.006 ms): write_hint/7576 fcntl(fd: 3, cmd: GET_RW_HINT, arg: 0x7ffc6c918da0) = -1 EINVAL Invalid argument 0.014 ( 0.004 ms): write_hint/7576 fcntl(fd: 4, cmd: GETFL) = 33794 # perf trace -e fcntl ./write_hint write_hint.c 1 fcntl: F_SET_RW_HINT: Invalid argument 0.000 ( 0.007 ms): write_hint/7578 fcntl(fd: 3, cmd: SET_RW_HINT, arg: 0x7fff03866d70) = -1 EINVAL Invalid argument 0.019 ( 0.002 ms): write_hint/7578 fcntl(fd: 4, cmd: GETFL) = 33794 #
