Quentin Young	74e4a329a3	lib: fix a few bugs in ring buffers ... * Fix rare failure caused when end pointer is at end of buffer memory and a call to ringbuf_get() is made that reads all of the data in the buffer; start pointer was advanced past end pointer, causing some special handling to be skipped * Fix ringbuf_peek() moving start pointer * Fix use after free * Remove extraneous assignment * Update relevant tests Signed-off-by: Quentin Young <qlyoung@cumulusnetworks.com>	2018-01-03 14:04:43 -05:00
Quentin Young	a5080622b2	lib: add ringbuf_peek() ... Peek functionality for ring buffers and associated tests.
