Summary
In the Linux kernel, the following vulnerability has been resolved:
xfs: fix unit conversions in per_binval computation
LOLLM noticed that we're doing the unit conversion in the per_binval computation backwards – xfs_buf_inval_log_space's second parameter is supposed to be in bytes, but max_binval is in units of fsblocks. Hence the conversion should be FSB -> B, not the other way around.
