If the change of personality does not lead to change of exec domain,
__set_personality() returned without releasing the module reference
acquired by lookup_exec_domain().

I found that the prototypes for sys_waitid and sys_fcntl in
<linux/syscalls.h> don't match the implementation. In order to keep all
prototypes in sync in the future, now include the header from each file
implementing any syscall.

These are only used by the out of tree linux-abi project, so it makes sense
to define them in those modules.

This cleans up a larger amount of superfluos ";;" statements in current
Linux kernel sources by converting them to the regular single ";"
statments.
It seems to be a common problem that at the end of a line the semicolon
key is producing an echo.

This is what a lot of the callers really wanted.
|
|
completly remove the old try_inc_mod_count()
|
|
A second start at removing them from kernel/*.c and fs/*.c.
Note that module_put is fine for a NULL argument.
|
|
Fixes crypto so it compiles with !CONFIG_MODULES, and cleans up two
other cases which did #ifdef CONFIG_MODULES.
|
|
This is an implementation of the in-kernel module loader extending
the try_inc_mod_count() primitive and making its use compulsory.
This has the benifit of simplicity, and similarity to the existing
scheme. To reduce the cost of the constant increments and
decrements, reference counters are lockless and per-cpu.
Eliminated (coming in following patches):
o Modversions
o Module parameters
o kallsyms
o EXPORT_SYMBOL_GPL and MODULE_LICENCE checks
o DEVICE_TABLE support.
New features:
o Typesafe symbol_get/symbol_put
o Single "insert this module" syscall interface allows trivial userspace.
o Raceless loading and unloading
You will need the trivial replacement module utilities from:

Updated maintainers list from Ingo's last ping,
various changed email addresses in code headers.

syscall latency improvement
* There's now an asm/thread_info.h header file with the basic structure
def and asm offsets in it.
* There's now a linux/thread_info.h header file which includes the asm
version and wraps some bitops calls to make convenience functions for
accessing the low-level flags.
* The task_struct has had some fields removed (and some flags), and has
acquired a pointer to the thread_info struct.
* task_struct's are now allocated on slabs in kernel/fork.c, whereas
thread_info structs are allocated at the bottom of the stack pages.
* Some more convenience functions are provided at the end of linux/sched.h to
access flags in other tasks (these are here because they need to access the
task_struct).
