Device-Mapper's "asm-striped" target is used to create a striped (i.e. RAID-0)
device across one or more underlying devices. Data is written in "chunks",
with consecutive chunks rotating among the underlying devices. This can
potentially provide improved I/O throughput by utilizing several physical
From: liuchaowei
The previous stripe index search algorithm use sequential search and
it's very slow if there are many and many physical storage devices.
The new alrogithm save the stripe index into stripe node structure,
and this driver will fetch stripe index from stripe node pointer
directly,
From: liuchaowei
This asymmetric stripe target device driver can achieve better io
performance between those devices which possess different io performance
There are 2 storage device or flash devices: A and B, their sequential
read performance are 220M/s and 315M/s respectively, so their sequent
The cgroup-v1 documentation is out of date in a few places:
* cgroup controllers can no longer be compiled as modules since commit
3ed80a6 ("cgroup: drop module support"); the functions and fields
referenced here no longer exist.
* Controllers need to create of a cgroup_subsys object name
The cgroup_subsys structure references a documentation file that has been
renamed after the v1/v2 split. Since the v2 documentation doesn't
currently contain any information on kernel interfaces for controllers,
point the user to the v1 docs.
