It includes a bug fix for a long standing race in the driver shutdown path. More people are stress testing the nvdimm configuration mechanism which is a welcome sign. There is also a rework of the infrastructure for looking up the dax_device associated with a block_device. This collided (silent conflict) with the erofs updates to add dax support this cycle. Gao Xiang noted this as well in the erofs pull request. Stephen's fix [1] looked correct to me. Otherwise, it has been in -next for a while with no other reported issues. Please pull, thanks, Dan [1]: https://lore.kernel.org/r/20210830170938.6fd8813d@canb.auug.org.au --- The following changes since commit e22ce8eb631bdc47a4a4ea7ecf4e4ba499db4f93: Linux 5.14-rc7 (2021-08-22 14:24:56 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm tags/libnvdimm-for-5.15 for you to fetch changes up to 3fc3725357414636d91be1558ce8b14f228b4bda: Merge branch 'for-5.15/fsdax-cleanups' into for-5.15/libnvdimm (2021-09-08 15:58:13 -0700) ---------------------------------------------------------------- libnvdimm for v5.15 - Fix a race condition in the teardown path of raw mode pmem namespaces. - Cleanup the code that filesystems use to detect filesystem-dax capabilities of their underlying block device. ---------------------------------------------------------------- Christoph Hellwig (9): fsdax: improve the FS_DAX Kconfig description and help text dax: stop using bdevname dm: use fs_dax_get_by_bdev instead of dax_get_by_host dax: mark dax_get_by_host static dax: move the dax_read_lock() locking into dax_supported dax: remove __generic_fsdax_supported dax: stub out dax_supported for !CONFIG_FS_DAX xfs: factor out a xfs_buftarg_is_dax helper dax: remove bdev_dax_supported Dan Williams (1): Merge branch 'for-5.15/fsdax-cleanups' into for-5.15/libnvdimm sumiyawang (1): libnvdimm/pmem: Fix crash triggered when I/O in-flight during unbind drivers/dax/super.c | 191 +++++++++++++++++++------------------------------- drivers/md/dm-table.c | 9 +-- drivers/md/dm.c | 2 +- drivers/nvdimm/pmem.c | 4 +- fs/Kconfig | 21 +++++- fs/ext2/super.c | 3 +- fs/ext4/super.c | 3 +- fs/xfs/xfs_super.c | 16 +++-- include/linux/dax.h | 41 ++--------- 9 files changed, 119 insertions(+), 171 deletions(-)
