Hi all
I am doing ftrace to track files being opened and mapped by process
but sys_enter_open is getting missed and getname is being traced which
is called by sys_open only. What is happening.?
mem-2474 [005] 681774.985957: getnameprobe: (sys_execve+0x21/0x5a <-
getname) arg1="bin/mem"
mem-2474 [001] 683183.894867: sync_read:
(vfs_read+0xab/0x107 <- do_sync_read) arg1=80
mem-2474 [001] 683183.894900: sync_read:
