Directory Notifications & FD arrays

[prasad Musale <prasad.musale@xxxxxxxxx>]

Hello Friends,

                   I have few questions:

1. Why we need directory notifications?

2. When get_unused_fd() is called in sys_open() what is the purpose behind expanding fdset & fd array?

3. What is fastcall (encountered in void fastcall fd_install())?

 

 

Thanks.
