In the Linux kernel, the following vulnerability has been resolved:
exfat: fix the new buffer was not zeroed before writing
Before writing, if a buffer_head marked as new, its data must be zeroed, otherwise uninitialized data in the page cache will be written.
So this commit uses foliozeronewbuffers() to zero the new buffers before ->writeend().
