2014-03-21crypto: crypto_wq - Fix late crypto work queue initializationTim Chen1-1/+1
The crypto algorithm modules utilizing the crypto daemon could be used early when the system start up. Using module_init does not guarantee that the daemon's work queue is initialized when the cypto alorithm depending on crypto_wq starts. It is necessary to initialize the crypto work queue earlier at the subsystem init time to make sure that it is initialized when used.

2011-10-31crypto: add module.h to those files that are explicitly using itPaul Gortmaker1-0/+1
Part of the include cleanups means that the implicit inclusion of module.h via device.h is going away. So fix things up in advance. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-01-04crypto: mark crypto workqueues CPU_INTENSIVETejun Heo1-1/+2
kcrypto_wq and pcrypt->wq's are used to run ciphers and may consume considerable amount of CPU cycles. Mark both as CPU_INTENSIVE so that they don't block other work items. As the workqueues are primarily used to burn CPU cycles, concurrency levels shouldn't matter much and are left at 1. A higher value may be beneficial and needs investigation.

2009-02-19crypto: api - Use dedicated workqueue for crypto subsystemHuang Ying1-0/+38
Use dedicated workqueue for crypto subsystem A dedicated workqueue named kcrypto_wq is created to be used by crypto subsystem. The system shared keventd_wq is not suitable for encryption/decryption, because of potential starvation problem.
