Linux Perf equivalent for: dtrace -n 'io:::start /execname == "kworker"/ { printf("%d %s %s", pid, execname, fileinfo_t}' -


i need like: 

dtrace -n 'io:::start /execname == "kworker"/ { printf("%d %s %s", pid, execname, fileinfo_t}'

using perf.. how do so? where's perf language documented? problem i'm facing this: have app generating write sdc - know app kworker need figure out why kworker doing (i'm using flash disk i'm write sensitive)?

i'm seeing lines in dmesg:

[17621.884263] kworker/u4:2(18327): write block 794104 on sdc1 (8 sectors)
