[PATCH] imsm: FIX: imsm_add_spare() wrongly tests spares list

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



For more than one disk tested additional_test_list was searched from last
point, not from begin.

This bug causes that more than 2 disks cannot be added to imsm array,
when imsm_add_spare() is used for this.
