system call

[Rajat Sharma]

search for SYSCALL_DEFINE<X>(syscall) in linux source e.g.

SYSCALL_DEFINE3(open, const char __user *, filename, int, flags, int,
mode) in fs/open.c

here <X> depends on number of arguments to system call: 3 in case of open.

you would find open, read, write and close in fs directory only.
