In linux kernel since version 2.6.24 (release Date: 2008-01-24)
If the MTD device admits of bad eraseblocks (e.g. NAND flash), UBI
reserves some amount of physical eraseblocks to handle new bad
eraseblocks. For example, if a flash physical eraseblock becomes bad,
UBI uses these reserved physical eraseblocks to relocate the bad one.
This option specifies how many physical eraseblocks will be reserved
for bad eraseblock handling (percents of total number of good flash
eraseblocks). If the underlying flash does not admit of bad
eraseblocks (e.g. NOR flash), this value is ignored and nothing is
reserved. Leave the default value if unsure.
