They have appeared in a -next release. However, note that commit d7782145e1ad (+ACI-filesystem-dax: Fix dax+AF8-layout+AF8-busy+AF8-page() livelock+ACI-) is immediately replaced with the Xarray conversion targeting 4.20, so d7782145e1ad is the backport suitable fix for the livelock for v4.19 and earlier. Please pull, thanks+ACE- --- The following changes since commit 17b57b1883c1285f3d0dc2266e8f79286a7bef38: Linux 4.19-rc6 (2018-09-30 07:15:35 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm tags/libnvdimm-fixes-4.19-rc8 for you to fetch changes up to 4628a64591e6cee181237060961e98c615c33966: mm: Preserve +AF8-PAGE+AF8-DEVMAP across mprotect() calls (2018-10-09 11:44:58 -0700) ---------------------------------------------------------------- libnvdimm/dax 4.19-rc8 +ACo- Fix a livelock in dax+AF8-layout+AF8-busy+AF8-page() present since v4.18.
