Summary
iomap: avoid avoid truncating 64-bit offset to 32 bits
Details

In the Linux kernel, the following vulnerability has been resolved:

iomap: avoid avoid truncating 64-bit offset to 32 bits

on 32-bit kernels, iomapwritedelallocscan() was inadvertently using a 32-bit position due to folionext_index() returning an unsigned long. This could lead to an infinite loop when writing to an xfs filesystem.
