This patch provides functions _scratch_dev_pool_get() _scratch_dev_pool_put() Which will help to set/reset SCRATCH_DEV_POOL with the required number of devices. SCRATCH_DEV_POOL_SAVED will hold all the devices. Usage: _scratch_dev_pool_get() <ndevs> :: do stuff _scratch_dev_pool_put() Signed-off-by: Anand Jain <anand.jain@oracle.com> --- common/rc | 47 +++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 47 insertions(+)
