9What: USER_SCHED
10When: 2.6.34
11
12Why: USER_SCHED was implemented as a proof of concept for group scheduling.
13 The effect of USER_SCHED can already be achieved from userspace with
14 the help of libcgroup. The removal of USER_SCHED will also simplify
15 the scheduler code with the removal of one major ifdef. There are also
16 issues USER_SCHED has with USER_NS. A decision was taken not to fix
17 those and instead remove USER_SCHED. Also new group scheduling
18 features will not be implemented for USER_SCHED.

53When: 2.6.36
54
55Why: The ioctls in kernel/power/user.c were marked as deprecated long time
56 ago. Now they notify users about that so that they need to replace
57 their userspace. After some more time, remove them completely.

91What: CONFIG_WIRELESS_OLD_REGULATORY - old static regulatory information
92When: March 2010 / desktop catchup
93
94Why: The old regulatory infrastructure has been replaced with a new one
95 which does not require statically defined regulatory domains. We do
96 not want to keep static regulatory domains in the kernel due to the
97 the dynamic nature of regulatory law and localization. We kept around
98 the old static definitions for the regulatory domains of:
99
100 * US
101 * JP
102 * EU
103
104 and used by default the US when CONFIG_WIRELESS_OLD_REGULATORY was
105 set. We will remove this option once the standard Linux desktop catches
106 up with the new userspace APIs we have implemented.

530When: 2.6.35
531Files: drivers/input/keyboard/{corgi,spitz,tosa}kbd.c
532Why: We now have a generic GPIO based matrix keyboard driver that
533 are fully capable of handling all the keys on these devices.
534 The original drivers manipulate the GPIO registers directly
535 and so are difficult to maintain.

545 that's to wait till vsync before ADC sampling, is also integrated into

547 and is difficult to maintain, it will be removed later.
