Andreas Kling	1b2ef8582c	Kernel: Make File's can_read/can_write take a const FileDescription& ... Asking a File if we could possibly read or write it will never mutate the asking FileDescription&, so it should be const.	2019-11-04 14:03:14 +01:00
Andreas Kling	c8e2bb5605	Kernel: Add a mechanism for listening for changes to an inode. ... The syscall is quite simple: int watch_file(const char* path, int path_length); It returns a file descriptor referring to a "InodeWatcher" object in the kernel. It becomes readable whenever something changes about the inode. Currently this is implemented by hooking the "metadata dirty bit" in Inode which isn't perfect, but it's a start. :^)	2019-07-22 20:01:11 +02:00
