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

gfs2: Truncate address space when flipping GFS2_DIF_JDATA flag

Truncate an inode's address space when flipping the GFS2_DIF_JDATA flag:
depending on that flag, the pages in the address space will either use
buffer heads or iomap_folio_state structs, and we cannot mix the two.
