Steven Rostedt c7b0930857 ring-buffer: prevent adding write in discarded area ... This a very tight race where an interrupt could come in and not have enough data to put into the end of a buffer page, and that it would fail to write and need to go to the next page. But if this happened when another writer was about to reserver their data, and that writer has smaller data to reserve, then it could succeed even though the interrupt moved the tail page. To pervent that, if we fail to store data, and by subtracting the amount we reserved we still have room for smaller data, we need to fill that space with "discarded" data. [ Impact: prevent race were buffer data may be lost ] Signed-off-by: Steven Rostedt <rostedt@goodmis.org>		2009-06-15 11:37:19 -04:00
