module_author: don't advise putting in an email address

module_author: don't advise putting in an email address

It's information that's easily outdated and easily mistaken for a driver
contact which is a problem especially for modules with multiple current and
non-current authors as well as for modules with a maintainer who may not
even be a module author.

Allow arch to initialize arch field of the module structure

2007-05-09T19:30:56+00:00

This will later allow an arch to add module specific information via linker
generated tables instead of poking directly in the module object structure.

Fix race between cat /proc/slab_allocators and rmmod

2007-05-08T18:15:08+00:00

Same story as with cat /proc/*/wchan race vs rmmod race, only
/proc/slab_allocators want more info than just symbol name.

Fix race between cat /proc/*/wchan and rmmod et al

2007-05-08T18:15:08+00:00

kallsyms_lookup() can go iterating over modules list unprotected which is OK
for emergency situations (oops), but not OK for regular stuff like
/proc/*/wchan.

Introduce lookup_symbol_name()/lookup_module_symbol_name() which copy symbol
name into caller-supplied buffer or return -ERANGE.  All copying is done with
module_mutex held, so...

Fix race between rmmod and cat /proc/kallsyms

2007-05-08T18:15:08+00:00

module_get_kallsym() leaks "struct module *" outside of module_mutex which is
no-no, because module can dissapear right after mutex unlock.

Copy all needed information from inside module_mutex into caller-supplied
space.

Simplify module_get_kallsym() by dropping length arg

2007-05-08T18:15:08+00:00

module_get_kallsym() could in theory truncate module symbol name to fit in
buffer, but nobody does this.  Always use KSYM_NAME_LEN + 1 bytes for name.

Suggested by lg^WRusty.

remove "struct subsystem" as it is no longer needed

2007-05-03T01:57:59+00:00

We need to work on cleaning up the relationship between kobjects, ksets and
ktypes.  The removal of 'struct subsystem' is the first step of this,
especially as it is not really needed at all.

Thanks to Kay for fixing the bugs in this patch.
