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: (vfs_read+0xab/0x107 <- do_sync_read) arg1=1c0 mem-2474 [001] 683183.894902: sync_read: (vfs_read+0xab/0x107 <- do_sync_read) arg1=1c mem-2474 [001] 683183.894913: sync_read: (vfs_read+0xab/0x107 <- do_sync_read) arg1=80 mem-2474 [001] 683183.895113: sync_read: (vfs_read+0xab/0x107 <- do_sync_read) arg1=188 mem-2474 [001] 683183.895275: getnameprobe: (do_sys_open+0x3b/0x105 <- getname) arg1="/etc/ld.so.cache" mem-2474 [001] 683183.895316: getnameprobe: (do_sys_open+0x3b/0x105 <- getname) arg1="/lib/libc.so.6" mem-2474 [001] 683183.895321: sys_read(fd: 4, buf: 7fff8461a0f8, count: 340) mem-2474 [001] 683183.895328: sync_read: (vfs_read+0xab/0x107 <- do_sync_read) arg1=340
