| * | block: add iostat counters for flush requests | Konstantin Khlebnikov | 2019-11-21 | 1 | -2/+12 |
| | | | | | | | | | | | | | | | | Requests that triggers flushing volatile writeback cache to disk (barriers) have significant effect to overall performance. Block layer has sophisticated engine for combining several flush requests into one. But there is no statistics for actual flushes executed by disk. Requests which trigger flushes usually are barriers - zero-size writes. This patch adds two iostat counters into /sys/class/block/$dev/stat and /proc/diskstats - count of completed flush requests and their total time.

| * | docs: block: convert to ReST | Mauro Carvalho Chehab | 2019-07-15 | 1 | -0/+93 |
| Rename the block documentation files to ReST, add an index for them and adjust in order to produce a nice html output via the Sphinx build system. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.
