[PATCH net-next 00/14] sctp: remove typedefs from structures part 4

[PATCH net-next 00/14] sctp: remove typedefs from structures part 4

[Xin Long]

As we know, typedef is suggested not to use in kernel, even checkpatch.pl
also gives warnings about it. Now sctp is using it for many structures.

All this kind of typedef's using should be removed. This patchset is the
part 4 to remove it for another 14 basic structures from linux/sctp.h.
After this patchset, all typedefs are cleaned in linux/sctp.h.

Just as the part 1-3, No any code's logic would be changed in these patches,
only cleaning up.

[PATCH net-next 01/14] sctp: remove the typedef sctp_shutdownhdr_t

[Xin Long]

This patch is to remove the typedef sctp_shutdownhdr_t, and
replace with struct sctp_shutdownhdr in the places where it's
using this typedef.

It is also to use sizeof(variable) instead of sizeof(type).

[PATCH net-next 02/14] sctp: fix the name of struct sctp_shutdown_chunk_t

[Xin Long]

This patch is to fix the name of struct sctp_shutdown_chunk_t
, replace with struct sctp_initack_chunk in the places where
it's using it.

It is also to fix some indent problem.

[PATCH net-next 11/14] sctp: remove the typedef sctp_addiphdr_t

[Xin Long]

This patch is to remove the typedef sctp_addiphdr_t, and
replace with struct sctp_addiphdr in the places where it's
using this typedef.

It is also to use sizeof(variable) instead of sizeof(type).

[PATCH net-next 00/14] sctp: remove typedefs from structures part 5

[Xin Long]

As we know, typedef is suggested not to use in kernel, even checkpatch.pl
also gives warnings about it. Now sctp is using it for many structures.

All this kind of typedef's using should be removed. This patchset is the
part 5 to remove all typedefs in include/net/sctp/constants.h.

Just as the part 1-4, No any code's logic would be changed in these patches,
only cleaning up.

Xin Long (14):
  sctp: remove the typedef sctp_lower_cwnd_t
  sctp: remove the typedef sctp_retransmit_reason_t
  sctp: remove the typedef sctp_scope_policy_t
  sctp: remove the typedef sctp_scope_t
  sctp: remove the typedef sctp_transport_cmd_t
  sctp: remove the typedef sctp_sock_state_t
  sctp: remove the typedef sctp_xmit_t
  sctp: remove the typedef sctp_ierror_t
  sctp: remove the typedef sctp_state_t
  sctp: remove the typedef sctp_event_primitive_t
  sctp: remove the typedef sctp_event_other_t
  sctp: remove the typedef sctp_event_timeout_t
  sctp: remove the typedef sctp_event_t
  sctp: remove the typedef sctp_subtype_t

[PATCH net-next 03/14] sctp: remove the typedef sctp_scope_policy_t

[Xin Long]

This patch is to remove the typedef sctp_scope_policy_t and keep
it's members as an anonymous enum.

It is also to define SCTP_SCOPE_POLICY_MAX to replace the num 3
in sysctl.c to make codes clear.

[PATCH net-next 14/14] sctp: remove the typedef sctp_subtype_t

[Xin Long]

This patch is to remove the typedef sctp_subtype_t, and
replace with union sctp_subtype in the places where it's
using this typedef.

Note that it doesn't fix many indents although it should,
as sctp_disposition_t's removal would mess them up again.
So better to fix them when removing sctp_disposition_t in
later patch.

Perhaps slightly better to end the enum with:

	SCTP_SCOPE_POLICY_MAX = SCTP_SCOPE_POLICY_COUNT - 1	/* Last policy */
};

It might be, so that new member coming will not change too much.

I just copied the idea of SCTP_EVENT_xxxx_MAX, SCTP_STATE_MAX :-)

[PATCH net-next 00/14] sctp: remove typedefs from structures part 6

[Xin Long]

As we know, typedef is suggested not to use in kernel, even checkpatch.pl
also gives warnings about it. Now sctp is using it for many structures.

All this kind of typedef's using should be removed. This patchset is the
part 6 to remove all typedefs in include/net/sctp/structs.h, command.h
and sm.h.

Just as the part 1-5, No any code's logic would be changed in these patches,
only cleaning up.

Note that this is the last part for this typedef cleaning up. after this
patchset, no more inappropriate typedefs in sctp. It's also to tidy some
codes when removing them, like fixing many indents, reodering some local
params, especially in the last 2 patches.

Xin Long (14):
  sctp: remove the unused typedef sctp_packet_phandler_t
  sctp: remove the typedef sctp_sender_hb_info_t
  sctp: remove the typedef sctp_endpoint_type_t
  sctp: remove the typedef sctp_cmsgs_t
  sctp: remove the typedef sctp_dbg_objcnt_entry_t

[Xin Long]

This patch is to remove the typedef sctp_sender_hb_info_t, and
replace with struct sctp_sender_hb_info in the places where it's
using this typedef.

It is also to use sizeof(variable) instead of sizeof(type).

[PATCH net-next 08/14] sctp: remove the typedef sctp_cmd_seq_t

[Xin Long]

This patch is to remove the typedef sctp_cmd_seq_t, and
replace with struct sctp_cmd_seq in the places where it's
using this typedef.

Note that it doesn't fix many indents although it should,
as sctp_disposition_t's removal would mess them up again.
So better to fix them when removing sctp_disposition_t in
the later patch.

[PATCH net-next 13/14] sctp: remove the typedef sctp_disposition_t

[Xin Long]

This patch is to remove the typedef sctp_disposition_t, and
replace with enum sctp_disposition in the places where it's
using this typedef.

It's also to fix the indent for many functions' defination.

[PATCH net-next 14/14] sctp: fix some indents in sm_make_chunk.c

[Xin Long]

There are some bad indents of functions' defination in sm_make_chunk.c.
They have been there since beginning, it was probably caused by that
the typedef sctp_chunk_t was replaced with struct sctp_chunk.

So it's the best time to fix them in this patchset, it's also to fix
some bad indents in other functions' defination in sm_make_chunk.c.

Re: [PATCH net-next 00/14] sctp: remove typedefs from structures part 6

Series applied, thanks Xin.
