kfifo: add parenthesis for macro parameter reference

2010-09-10T01:57:22+00:00

Some macro parameter references inside typeof() operator are not enclosed
with parenthesis.  It should be safer to add them.

kfifo: implement missing __kfifo_skip_r()

2010-08-20T16:34:54+00:00

kfifo_skip() is currently broken, due to the missing of the internal
helper function.  Add it.

kfifo: replace the old non generic API

2010-08-11T15:59:23+00:00

Simply replace the whole kfifo.c and kfifo.h files with the new generic
version and fix the kerneldoc API template file.

kfifo: kfifo_is_{full,empty} should return bools, not ints

2010-08-11T15:59:23+00:00

For consistency with other kfifo routines, return bool, not int.

include/linux/kfifo.h: fix INIT_KFIFO()

2010-04-07T15:38:02+00:00

DECLARE_KFIFO creates a union with a struct kfifo and a buffer array with
size [size + sizeof(struct kfifo)].

INIT_KFIFO then sets the buffer pointer in struct kfifo to point to the
beginning of the buffer array which means that the first call to kfifo_in
will overwrite members of the struct kfifo.

kfifo: fix KFIFO_INIT in include/linux/kfifo.h

2010-03-24T23:31:20+00:00

include/linux/kfifo.h first defines and then undefines __kfifo_initializer
which is used by INIT_KFIFO (which is also a macro, so building a module
which uses INIT_KFIFO will fail).

kfifo: fix kerneldoc for kfifo_avail and kfifo_in_locked

2010-03-18T00:24:38+00:00

Function argument is not having "len" anywhere;
"len" is later used in kfifo_{in|out}.

So here, it would be appropriate to say,
it copies @n bytes and not @len

kfifo: document everywhere that size has to be power of two

2010-01-16T20:15:38+00:00

On my first try using them I missed that the fifos need to be power of
two, resulting in a runtime bug.  Document that requirement everywhere
(and fix one grammar bug)
