Changes[edit]

Since 042stab065.3:

  • [mm] possible memory corruption has been fixed by preventing reclaiming of pages in the writeback (PSBM-16442)
  • [ploop] possible deadlock on destroying map has been fixed (PSBM-16627)
  • [ubc/mm] A new strict page cache isolation feature (PSBM-16955, see Page cache isolation)
