irda: Fix lockdep annotations in hashbin_delete().

2017-02-17T21:19:39+00:00

A nested lock depth was added to the hasbin_delete() code but it
doesn't actually work some well and results in tons of lockdep splats.

Fix the code instead to properly drop the lock around the operation
and just keep peeking the head of the hashbin queue.

Replace with globally

2016-12-24T19:46:01+00:00

This was entirely automated, using the script by Al:

  PATT='^[[:blank:]]*#[[:blank:]]*include[[:blank:]]*'
  sed -i -e "s!$PATT!#include !" \
        $(git grep -l "$PATT"|grep -v ^include/linux/uaccess.h)

to do the replacement at the end of the merge window.

irda: irnet: add member name to the miscdevice declaration

2016-12-17T16:29:31+00:00

Since the struct miscdevice have many members, it is dangerous to init
it without members name relying only on member order.

This patch add member name to the init declaration.

irnet: ppp: move IRNET_MINOR to include/linux/miscdevice.h

2016-12-17T16:17:24+00:00

This patch move the define for IRNET_MINOR to include/linux/miscdevice.h
It is better that all minor number definitions are in the same place.

irda: irnet: Move linux/miscdevice.h include

2016-12-17T16:16:31+00:00

The only use of miscdevice is irda_ppp so no need to include
linux/miscdevice.h for all irda files.
This patch move the linux/miscdevice.h include to irnet_ppp.h

irproc.c does not use any miscdevice so this patch remove this
unnecessary inclusion.

genetlink: mark families as __ro_after_init

2016-10-27T20:16:09+00:00

Now genl_register_family() is the only thing (other than the
users themselves, perhaps, but I didn't find any doing that)
writing to the family struct.

In all families that I found, genl_register_family() is only
called from __init functions (some indirectly, in which case
I've add __init annotations to clarifly things), so all can
actually be marked __ro_after_init.

This protects the data structure from accidental corruption.

genetlink: statically initialize families

2016-10-27T20:16:09+00:00

Instead of providing macros/inline functions to initialize
the families, make all users initialize them statically and
get rid of the macros.

This reduces the kernel code size by about 1.6k on x86-64
(with allyesconfig).

genetlink: no longer support using static family IDs

2016-10-27T20:16:09+00:00

Static family IDs have never really been used, the only
use case was the workaround I introduced for those users
that assumed their family ID was also their multicast
group ID.

Additionally, because static family IDs would never be
reserved by the generic netlink code, using a relatively
low ID would only work for built-in families that can be
registered immediately after generic netlink is started,
which is basically only the control family (apart from
the workaround code, which I also had to add code for so
it would reserve those IDs)

Thus, anything other than GENL_ID_GENERATE is flawed and
luckily not used except in the cases I mentioned. Move
those workarounds into a few lines of code, and then get
rid of GENL_ID_GENERATE entirely, making it more robust.
