Hi all,
This patchset (stable page writes, part 2) makes some key modifications to
the original 'stable page writes' patchset. First, it provides creators
(devices and filesystems) of a backing_dev_info a flag that declares whether or
not it is necessary to ensure that page contents cannot
Create a helper function to check if a backing device requires stable page
writes and, if so, performs the necessary wait. Then, make it so that all
points in the memory manager that handle making pages writable use the helper
function. This should provide stable page write support to most
Several complaints have been received regarding long file write latencies when
memory pages must be held stable during writeback. Since it might not be
acceptable to stall programs for the entire duration of a page write (which may
take many milliseconds even on good hardware), enable a second
Fix up the -page_mkwrite handler to provide stable page writes if necessary.

This creates a per-backing-device flag that tracks whether or not pages must be
held immutable during writeout. Eventually it will be used to waive
wait_for_page_writeback() if nobody requires stable pages.

Some DVM regulators needs to update activate_bit after setting vsel_reg to
initiate voltage change on the output. This patch adds activate_reg and
activate_bit to struct regulator_desc and update
regulator_set_voltage_sel_regmap() to set activate_bit of activate_reg when
activate_bit is set.
We scale stime, utime values based on rtime (sum_exec_runtime converted
to jiffies). During scaling we multiple rtime * utime, what seems to be
fine, since both values are converted to u64, but is not.
Let assume HZ is 1000 - 1ms tick. Process consist of 64 threads, run
for 1 day, threads utilize

I don't know whether single driver could be used for both mms114 and mms144.
Couldn't find datasheets for any of them.

There's missing change for hists__precompute to iterate either
entries_collapsed or entries_in tree. The change was initiated
for hists_compute_resort function in commit:
2a2d3ce perf diff: Use internal rb tree for compute resort
but was missing for hists__precompute function changes.
The current logic is to attach pair to the leader hist_entry.
Arguments of hist_entry__add_pair function were placed
the other way round.. driving me crazy.

Making the baseline hists to act as a pairs head.
So far we don't care which hists act as a pairs head, because
we have only 2 files to deal with and any of them is suitable
to do the job.
But if we want to process more files, we need to pick up one

It does not make sense to make some computation (ratio, wdiff),
when the hist_entry is 'dummy' - added via hists__link.
Adding dummy field to struct hist_entry which indicates
that it was added by hists__link and avoiding some of
the processing for such entries.

Adding diff command the flexibility to specify multiple data
files on input. If not input file is given the standard behaviour
stands and diff inspects 'perf.data' and 'perf.data.old' files.
