[RFC] dm-bow working prototype

bow == backup on write Similar to dm-snap, add the ability to take a snapshot of a device. Unlike dm-snap, a separate volume is not required. dm-bow can be in one of three states. In state one, the free blocks on the device are identified by issuing an FSTRIM to the filesystem. In state two, an

[PATCH v2] Documentation/proc.txt: Add 2 missing fields for /proc//status

[PATCH 0/6] Coordinated Clks

Here's the first set of patches that I'm working on for the Common Clk Framework. Part of this patch series adds a new clk op, pre_rate_req. This is designed to replace the clk notifier approach that many clk drivers use right now to setup alt parents or temporary dividers. This should allow for th

[PATCH 5/6] docs: driver-api: add pre_rate_req to clk documentation

This adds documentation for the new clk op pre_rate_req. Signed-off-by: Derek Basehore --- Documentation/driver-api/clk.rst | 7 ++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/Documentation/driver-api/clk.rst b/Documentation/driver-api/clk.rst index 593cca5058b1..917f6ac296

[PATCH 6/6] clk: rockchip: use pre_rate_req for cpuclk

This makes the rockchip cpuclk use the pre_rate_req op to change to the alt parent instead of the clk notifier. This has the benefit of the clk not changing parents behind the back of the common clk framework. It also changes the divider setting for the alt parent to only divide when the alt parent

[PATCH 2/6] clk: fix clk_calc_subtree compute duplications

clk_calc_subtree was called at every step up the clk tree in clk_calc_new_rates. Since it recursively calls itself for its children, this means it would be called once on each clk for each step above the top clk is. This fixes this by breaking the subtree calculation into two parts. The first part

[PATCH 3/6] clk: change rates via list iteration

This changes the clk_set_rate code to use lists instead of recursion. While making this change, also add error handling for clk_set_rate. This means that errors in the set_rate/set_parent/set_rate_and_parent functions will not longer be ignored. When an error occurs, the clk rates and parents are r

[PATCH 4/6] clk: add pre clk changes support

This adds a new clk_op, pre_rate_req. It allows clks to setup an intermediate state when clk rates are changed. One use case for this is when a clk needs to switch to a safe parent when its PLL ancestor changes rates. This is needed when a PLL cannot guarantee that it will not exceed the new rate b

[PATCH 1/6] clk: Remove recursion in clk_core_{prepare,enable}()

From: Stephen Boyd Enabling and preparing clocks can be written quite naturally with recursion. We start at some point in the tree and recurse up the tree to find the oldest parent clk that needs to be enabled or prepared. Then we enable/prepare and return to the caller, going back to the clk we
