LU-5549 llite: make default_easize writeable in /proc
Allow default_easize to be tuned via /proc. A system administrator
might want this if a rare access to widely striped files drives up the
value on a filesystem where narrowly striped files are the more common
case. In practice, however, this is wanted primarily to facilitate
a test case for LU-5549.
- Plumb the necessary interfaces through the LMV and MDC layers
to expose write access to this value by higher layers.
- Add block comments to modified functions.
- Correct misspelling of "default" in /proc handler function names
in lustre/llite/lproc_llite.c. The file names in /proc were already
spelled correctly so there are no issues with backward
compatibility.
- Convert remaining space-indented lines in lmv_set_info_async()
to tabs.
