bpqether: fix rcu usage

2007-07-31T22:39:40+00:00

The rcu_dereference() primitive needs to be applied to an l-value in order to
ensure that compiler writers don't get an opportunity to apply reordering
optimizations that could result in multiple fetches or in other misbehavior.
This patch pulls the rcu_dereference() calls in bpq_seq_next() up to the point
at which the fetched pointers are still l-values, rather than after
list_entry() has transformed them into r-values.

some kmalloc/memset ->kzalloc (tree wide)

2007-07-19T17:04:50+00:00

Transform some calls to kmalloc/memset to a single kzalloc (or kcalloc).

Here is a short excerpt of the semantic patch performing
this transformation:

usermodehelper: Tidy up waiting

2007-07-18T15:47:40+00:00

Rather than using a tri-state integer for the wait flag in
call_usermodehelper_exec, define a proper enum, and use that.  I've
preserved the integer values so that any callers I've missed should
still work OK.

baycom_ser_fdx: also allow i/o ports >= 0x1000 and enhanced failure logging

2007-04-28T15:01:02+00:00

The baycom_ser_fdx driver did not allow i/o ports >= 0x1000.  Now that
there are pci cards (with rs232 ports) which use for example 0xb800 this
limit should not exists.

Also, for non kernel coders find the cause of problems was challenging so I
added extra logging.

[SK_BUFF]: Introduce skb_copy_from_linear_data{_offset}

2007-04-26T05:28:23+00:00

To clearly state the intent of copying from linear sk_buffs, _offset being a
overly long variant but interesting for the sake of saving some bytes.

[SK_BUFF]: Introduce skb_reset_network_header(skb)

2007-04-26T05:24:46+00:00

For the common, open coded 'skb->nh.raw = skb->data' operation, so that we can
later turn skb->nh.raw into a offset, reducing the size of struct sk_buff in
64bit land while possibly keeping it as a pointer on 32bit.

This one touches just the most simple case, next will handle the slightly more
"complex" cases.
