2005-07-12[PATCH] inotifyRobert Love
inotify is intended to correct the deficiencies of dnotify, particularly its inability to scale and its terrible user interface: * dnotify requires the opening of one fd per each directory that you intend to watch. This quickly results in too many open files and pins removable media, preventing unmount. * dnotify is directory-based. You only learn about changes to directories. Sure, a change to a file in a directory affects the directory, but you are then forced to keep a cache of stat structures. * dnotify's interface to user-space is awful. Signals? inotify provides a more usable, simple, powerful solution to file change notification: * inotify's interface is a system call that returns a fd, not SIGIO. You get a single fd, which is select()-able. * inotify has an event that says "the filesystem that the item you were watching is on was unmounted." * inotify can watch directories or files. Inotify is currently used by Beagle (a desktop search infrastructure), Gamin (a FAM replacement), and other projects. See Documentation/filesystems/inotify.txt.

2005-04-27[PATCH] NFS4: Don't use __user with compat_uptr_tDavid Howells
The attached patch removes __user from compat_uptr_t types in the NFS4 mount 32-bit->64-bit compatibility structures. Signed-Off-By: David Howells <dhowells@redhat.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-04-18[PATCH] Add 32-bit compatibility for NFSv4 mountDavid Howells
This adds 32-bit compatibility for mounting an NFSv4 mount on a 64-bit kernel (such as happens with PPC64). The problem is that the mount data for the NFS4 mount process includes auxilliary data pointers, probably because the NFS4 mount data may conceivably exceed PAGE_SIZE in size - thus breaking against the hard limit imposed by sys_mount().

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
