[PATCH] I2O: Bugfixes to get I2O working again
From: Markus Lidel <Markus.Lidel@shadowconnect.com> - Fixed locking of struct i2o_exec_wait in Executive-OSM - Removed LCT Notify in i2o_exec_probe() which caused freeing memory and accessing freed memory during first enumeration of I2O devices - Added missing locking in i2o_exec_lct_notify() - removed put_device() of I2O controller in i2o_iop_remove() which caused the controller structure get freed to early - Fixed size of mempool in i2o_iop_alloc() - Fixed access to freed memory in i2o_msg_get() See http://bugzilla.kernel.org/show_bug.cgi?id=6561 Signed-off-by: Markus Lidel <Markus.Lidel@shadowconnect.com> Cc: <stable@kernel.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
