v2:
- In badblocks_free, make 'page' NULL (patch 1)
- Move the core badblocks code to a new .c file (patch 1) (Jens)
- Fix a sizeof usage in disk_alloc_badblocks (patch 2) (Dan)
- Since disk_alloc_badblocks can fail, check disk->bb for NULL in the
genhd wrappers (patch 2) (Jeff)
- Update the md conversion to also ise the badblocks init and free
functions (patch 3)
- Remove the BB_* macros from md.h as they are now in badblocks.h (patch 3)
Patch 1 copies badblock management code into a header of its own,
making it generally available. It follows common libraries of code
such as linked lists, where anyone may embed a core data structure
in another place, and use the provided accessor functions to
manipulate the data.
Patch 2 adds badblock tracking to gendisks (in preparation for use
by NVDIMM devices). Right now, it is turned on unconditionally - I'd
appreciate comments on if that is the right path.
Patch 3 converts md over to use the new badblocks 'library'. I have
done some pretty simple testing on this - created a raid 1 device,
made sure the sysfs entries show up, and can be used to add and view
badblocks. A closer look by the md folks would be nice here.
