This update added new revisions after undoing existing revisions. That is
to say, the old revision is not a strict subset of the new revision. This
situation occurs when you --force push a change and generate a repository
containing something like this:
* -- * -- B -- O -- O -- O (9d670d2889578bcd82fb2d985e78508bfc342a49)
\
N -- N -- N (e30da12106f8c6a23cd1e6be028d3a64877213d8)
When this happens we assume that you've already had alert emails for all
of the O revisions, and so we here report only the revisions in the N
branch from the common base, B.
Those revisions listed above that are new to this repository have
not appeared on any other notification email; so we list those
revisions in full, below.

[FIX] ProcFS:
the proc_root_fs variable is not available any more (and
non-existent, for that matter). Instead, file systems should
register themselves with the "fs/FS_NAME" name syntax, leaving
the parent proc_dir as NULL.
Also, the write_proc function should return an int, not a ssize_t.
The "owner" field is no longer available as part of the proc_dir_entry
structure. Following other file systems' example, it was simple
removed from the code (apparently, there's another way of keeping
track of processes using a proc entry)
[FIX] Fixed a printk - when printing long ints, %ld should be used
[FIX] super_operations
the signature of umount changed - now there's only one argument - the
super_block which should be unmounted.
There are still other issues concerning the super_operations structure
that need to be solved - see ticket #7
[FIX] simple_set_mnt does not return an error code any more. However,
looking at other file systems, they seem just to use it "as-is", so
probably we should remove the code below it (which used to handle
error cases)

commit 8f6cb18b661235e591b33504349f031d2021e59a
Author: Marko Obrovac <mar...@in...>
Date: Sun Oct 18 22:23:21 2009 +0200
[FIX] ProcFS:
the proc_root_fs variable is not available any more (and
non-existent, for that matter). Instead, file systems should
register themselves with the "fs/FS_NAME" name syntax, leaving
the parent proc_dir as NULL.
Also, the write_proc function should return an int, not a ssize_t.
The "owner" field is no longer available as part of the proc_dir_entry
structure. Following other file systems' example, it was simple
removed from the code (apparently, there's another way of keeping
track of processes using a proc entry)
[FIX] Fixed a printk - when printing long ints, %ld should be used
[FIX] super_operations
the signature of umount changed - now there's only one argument - the
super_block which should be unmounted.
There are still other issues concerning the super_operations structure
that need to be solved - see ticket #7
[FIX] simple_set_mnt does not return an error code any more. However,
looking at other file systems, they seem just to use it "as-is", so
probably we should remove the code below it (which used to handle
error cases)
