| |
3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Shmulik Ladkani <shmulik.ladkani@gmail.com>
commit 7bb9c75436212813b38700c34df4bbb6eb82debe upstream.
The code responsible for reading the version of the mirror bbt was incorrectly using the descriptor of the main bbt.
Pass the mirror bbt descriptor to 'scan_read_raw' when reading the version of the mirror bbt.
