force_ro Enforce read-only access even if write protect switch is off.
- num_wr_reqs_to_start_packing This attribute is used to determine
- the trigger for activating the write packing, in case the write
- packing control feature is enabled.
-
- When the MMC manages to reach a point where num_wr_reqs_to_start_packing
- write requests could be packed, it enables the write packing feature.
- This allows us to start the write packing only when it is beneficial
- and has minimum affect on the read latency.
-
- The number of potential packed requests that will trigger the packing
- can be configured via sysfs by writing the required value to:
- /sys/block/<block_dev_name>/num_wr_reqs_to_start_packing.
-
- The default value of num_wr_reqs_to_start_packing was determined by
- running parallel lmdd write and lmdd read operations and calculating
- the max number of packed writes requests.

+ This option enables the CPU frequency switch profiler. A file is
+ created in debugfs called "cpu_freq_switch_profile_enabled", which
+ defaults to zero. When a 1 is echoed into this file, profiling begins.
+ When a zero is echoed, profiling stops. A "cpu_freq_switch" file is
