[PATCH] s390/cio: Fix how vfio-ccw checks pinned pages

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

 



We have two nested loops to check the entries within the pfn_array_table
arrays.  But we mistakenly use the outer array as an index in our check,
and completely ignore the indexing performed by the inner loop.
