Thorsten Knabe 2a2361228c um: ubd: Fix for processes stuck in D state forever ... Starting with Linux 3.12 processes get stuck in D state forever in UserModeLinux under sync heavy workloads. This bug was introduced by commit 805f11a0d5 (um: ubd: Add REQ_FLUSH suppport). Fix bug by adding a check if FLUSH request was successfully submitted to the I/O thread and keeping the FLUSH request on the request queue on submission failures. Fixes: 805f11a0d5 (um: ubd: Add REQ_FLUSH suppport) Signed-off-by: Thorsten Knabe <linux@thorsten-knabe.de> Cc: stable@kernel.org # >= 3.12 Signed-off-by: Richard Weinberger <richard@nod.at>		2014-10-13 21:45:55 +02:00
