__devinit and __devexit removed in kernel ?

[Raj Ravi]

Hi,
 __devinit and __devexit removed from recent kernel (3.10 ? )

This was helpful to save some memory (to discard from memory once
execution is done in case of __devexit).

Any specific reason why this is removed ? any pointers?

Thanks

    But CONFIG_HOTPLUG and __devinit are now gone, and the need for the __ref
    annotations is also gone, so remove them.  Relevant historical commits:

    Remove __dev* markings from init.h
    
    Now that all in-kernel users of __dev* are gone, let's remove them from
    init.h to keep them from popping up again and again.
    
    Thanks to Bill Pemberton for doing all of the hard work to make removal
    of this possible.

Apparently all this had to do with the removal of the Kconfig symbol
HOTPLUG. Which was done in commit 40b313608ad4 ("Finally eradicate
CONFIG_HOTPLUG").

Hope this helps.
