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