Sorry for not replying earlier. However, in the mean time, you probably
have learned that Samsung has discontinued the Artik module/processor
family (see
http://www.businesskorea.co.kr/news/articleView.html?idxno=27384) for
example. So I don't think there's much sense to have a defconfig for a
Artik platform.

Best regards,

Thomas

+Subject: [PATCH] Btrfs: fix not being able to find skinny extents during
+ relocate
+
+We unconditionally search for the EXTENT_ITEM_KEY for metadata during balance,
+and then check the key that we found to see if it is actually a
+METADATA_ITEM_KEY, but this doesn't work right because METADATA is a higher key
+value, so if what we are looking for happens to be the first item in the leaf
+the search will dump us out at the previous leaf, and we won't find our item.
+So instead do what we do everywhere else, search for the skinny extent first and
+if we don't find it go back and re-search for the extent item.  This patch fixes
+the panic I was hitting when balancing a large file system with skinny extents.
+Thanks,
