[PATCH] omap2_mcspi.c: NULL pointer dereference
Check spi->controller_state before dereferencing. Shows up NULL here when using spi_alloc_device()/spi_add_device() and spi_add_device() fails before spi_setup(). Calling spi_dev_put() on the leftover spi_device results in the error. Signed-off-by: Scott Ellis <scott(a)jumpnowtek.com> drivers/spi/omap2_mcsp... 23 Feb 2010 17:02

Peer unexpectedly shrunk window
OK, the "Treason uncloaked" messages have been reworded[0][1] to now say "Peer [...] unexpectedly shrunk window", but the messages continue to appear. On a small Tor node (~100KB/s, ~200 connections) I'm getting ~2000 or so messages per month in my kernel log (and on the console). I see that it's logged with... 23 Feb 2010 15:51
