[PATCH 0/2] dm: add asymmetric stripe device driver

2017-12-29 Thread liuchaowei110
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

[PATCH 2/2] dm: optimze stripe index search algorithm

2017-12-29 Thread liuchaowei110
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,

[PATCH 1/2] dm: add asymmetric stripe target device dirver

2017-12-29 Thread liuchaowei110
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

[PATCH 1/2] Documentation/cgroup-v1: fix outdated programming details

2017-12-29 Thread Matt Roper
The cgroup-v1 documentation is out of date in a few places: * cgroup controllers can no longer be compiled as modules since commit 3ed80a6 ("cgroup: drop module support"); the functions and fields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

[PATCH 2/2] cgroup: Update documentation reference

2017-12-29 Thread Matt Roper
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. Cc: Tejun Heo Cc: linux-doc@vger.kernel.org Signed-of
