kfifo: fix inaccurate comment

2018-03-27T09:15:42+00:00

The comment in __kfifo_alloc says we round down, but we actually round up, so correct it. Signed-off-by: Martin Kelly Signed-off-by: Jiri Kosina

kfifo: use BUG_ON

2014-08-08T22:57:25+00:00

Use BUG_ON(x) rather than if(x) BUG(); The semantic patch that fixes this problem is as follows: // @@ identifier x; @@ -if (!x) BUG(); +BUG_ON(!x); // Signed-off-by: Himangi Saraogi Acked-by: Julia Lawall Cc: Stefani Seibold Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

kfifo: kfifo_copy_{to,from}_user: fix copied bytes calculation

2013-11-15T00:32:23+00:00

'copied' and 'len' are in bytes, while 'ret' is in elements, so we need to multiply 'ret' with the size of one element to get the correct result. Signed-off-by: Lars-Peter Clausen Cc: Stefani Seibold Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

kfifo: fix kfifo_alloc() and kfifo_init()

2013-02-28T03:10:23+00:00

Fix kfifo_alloc() and kfifo_init() to alloc at least the requested number of elements. Since the kfifo operates on power of 2 the request size will be rounded up to the next power of two. Signed-off-by: Stefani Seibold Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
