[RFC v5] UBI: Fastmap support (aka checkpointing)
|
|
This is a bug-fix release. v4 handled static volumes wrong.
v6 will address everything that Artem pointed out.
v1: https://lwn.net/Articles/481612/
v2: https://lwn.net/Articles/496586/
v3: Didn't release it to linux-mtd
v4: http://article.gmane.org/gmane.linux.kernel/1297626
Changes since v1:
- renamed it to UBIVIS (at least in Kconfig)
- UBIVIS parameters are now configurable via Kconfig
- several bugs have been fixed (design and implementation bugs)
- added lots of comments to make the review process easier
- made checkpatch.pl happy
Changes since v2:
- minor bugs have been fixed
- renamed it to UBI fastmap (as Artem requested)
Changes since v3:
- changed the on-flash layout (added padding fields, turned the
EBA storage into an array)
- fixed some corner cases (the protection queue needed some extra work)
- removed the data type hint logic
- rebased to Artems mtd tree
Changes since v4:
- fixed static volume handling (used_ebs and last_data_bytes contained
bad values in some cases)
