On the path to debugging why the dax memory-failure injection test started failing after the Xarray conversion a couple more fixes for the dax+AF8-lock+AF8-mapping+AF8-entry(), now called dax+AF8-lock+AF8-page(), surfaced. Those plus the bug that started the hunt are now addressed. These patches have appeared in a -next release with no issues reported. Note the touches to mm/memory-failure.c are just the conversion to the new function signature for dax+AF8-lock+AF8-page(). --- The following changes since commit 2e6e902d185027f8e3cb8b7305238f7e35d6a436: Linux 4.20-rc4 (2018-11-25 14:19:31 -0800) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm tags/dax-fixes-4.20-rc6 for you to fetch changes up to 27359fd6e5f3c5db8fe544b63238b6170e8806d8: dax: Fix unlock mismatch with updated API (2018-12-04 21:32:00 -0800) ---------------------------------------------------------------- dax fixes 4.20-rc6 +ACo- Fix the Xarray conversion of fsdax to properly handle dax+AF8-lock+AF8-mapping+AF8-entry() in the presense of pmd entries. +ACo- Fix inode destruction racing a new lock request. ---------------------------------------------------------------- Matthew Wilcox (3): dax: Check page-+AD4-mapping isn't NULL dax: Don't access a freed inode dax: Fix unlock mismatch with updated API fs/dax.c +AHw- 55 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+------------------ include/linux/dax.h +AHw- 14 +-+-+-+-+-+-+-+------- mm/memory-failure.c +AHw- 6 +-+-+-+--- 3 files changed, 50 insertions(+-), 25 deletions(-)
