[PATCH 1/2] hfsplus: fix overflow in sector calculations in hfsplus_submit_bio

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

 



The variable io_size was unsigned int, which caused the wrong sector number
to be calculated after aligning it. This then caused mount to fail with big
volumes, as backup volume header information was searched from a
wrong sector.
