Thanks!

I've noticed a diff in the Kconfig describing MTD_UBI_BEB_LIMIT.

In my original [PATCH 2/5] "ubi: Limit amount of reserved eraseblocks
for bad PEB handling" I've amended the MTD_UBI_BEB_LIMIT explanation a
bit.

The diff between what's on linux-ubi and my suggested description is:

-	  This option specifies the maximum bad physical eraseblocks UBI
-	  expects on the UBI device (percents of total number of physical
-	  eraseblocks on this MTD partition). If the underlying flash does not
-	  admit of bad eraseblocks (e.g. NOR flash), this value is ignored.
+	  If the MTD device admits of bad eraseblocks (e.g. NAND flash), UBI
+	  reserves some amount of physical eraseblocks to handle new bad
+	  eraseblocks.
+	  This option specifies the maximum bad eraseblocks UBI expects on the
+	  ubi device (percents of total number of flash eraseblocks).
+	  This limit is used in order to derive amount of eraseblock UBI
+	  reserves for handling new bad blocks.
+	  If the device has more bad eraseblocks than this limit, UBI does not
+	  reserve any physical eraseblocks for new bad eraseblocks, but
+	  attempts to use available eraseblocks (if any).
+	  If the underlying flash does not admit of bad eraseblocks (e.g. NOR
+	  flash), this value is ignored.

Just wanted to make sure you deliberately discarded these amendments.
