Field Documentation

action_in_progress

uint32_t spdk_bdev_module::__bdev_module_internal_fields::action_in_progress

Count of bdev inits/examinations in progress.

Used by generic bdev layer and must not be modified by bdev modules.

Note

Used internally by bdev subsystem, don't change this value in bdev module.

spinlock

struct spdk_spinlock spdk_bdev_module::__bdev_module_internal_fields::spinlock
