kfifo: fix kfifo_alloc() to return a signed int value

2010-10-28T01:03:18Z

Add a new __kfifo_int_must_check_helper() helper function, which is needed for kfifo_alloc() to return the right signed integer value. The origin __kfifo_must_check_helper() helper was renamed into __kfifo_uint_must_check_helper() to show the sign which is expected and returned. (And revert the temporary disabling of __kfifo_must_check_helper()) Signed-off-by: Stefani Seibold Acked-by: Randy Dunlap Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

kfifo: disable __kfifo_must_check_helper()

2010-10-26T23:52:04Z

This helper is wrong: it coerces signed values into unsigned ones, so code such as if (kfifo_alloc(...) < 0) { error } will fail to detect the error. So let's disable __kfifo_must_check_helper() for 2.6.36. Cc: Randy Dunlap Cc: Stefani Seibold Cc: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

kfifo: add parenthesis for macro parameter reference

2010-09-10T01:57:22Z

Some macro parameter references inside typeof() operator are not enclosed with parenthesis. It should be safer to add them. Signed-off-by: Huang Ying Acked-by: Stefani Seibold Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

kfifo: implement missing __kfifo_skip_r()

2010-08-20T16:34:54Z

kfifo_skip() is currently broken, due to the missing of the internal helper function. Add it. Signed-off-by: Andrea Righi Cc: Greg KH Acked-by: Stefani Seibold Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

kfifo: replace the old non generic API

2010-08-11T15:59:23Z

Simply replace the whole kfifo.c and kfifo.h files with the new generic version and fix the kerneldoc API template file. Signed-off-by: Stefani Seibold Cc: Greg KH Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

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

2010-08-11T15:59:23Z

For consistency with other kfifo routines, return bool, not int. Signed-off-by: Robert P. J. Day Cc: Stefani Seibold Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

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

2010-04-07T15:38:02Z

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

2010-03-24T23:31:20Z

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

2010-03-18T00:24:38Z

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 Signed-off-by: Viral Mehta Signed-off-by: Jiri Kosina
