UBI patches for 2.6.36

Hi,

I'm going to send the following patches to Linus soonish, any objections?

Best Regards,

list_for_each_entry uses its first argument to move from one element to the next, so modifying it can break the iteration. The variable re1 is already used within the loop as a temporary variable, and is not live here.

The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@r@
iterator name list_for_each_entry;
expression x,E;
position p1,p2;
@@

list_for_each_entry@p1(x,...) { <... x =@p2 E ...> }

@@
expression x,E;
position r.p1,r.p2;
statement S;
@@

*x =@p2 E
...
list_for_each_entry@p1(x,...) S
// </smpl>

1.7.2.2

From: Artem Bityutskiy <[email protected]>

Commit 0798cea8c2e1afee59686c51d27d0e96b05e42d1 "UBI: improve corrupted flash handling" broke delet-compatible volumes handling - it introduced a limit of 8 eraseblocks which may be corrupted. And delete-compatible eraseblocks are added to the "corrupted" list, so if we'd have a large delete-compatible volume, UBI would refuse it.

The fix is to add delete-compatible volumes to the erase list instead. Indeed, they are corrupted, we just have to erase them.
