[PATCH v2 09/11] ext2: add support for DAX fsync/msync
To properly support the new DAX fsync/msync infrastructure filesystems need to call dax_pfn_mkwrite() so that DAX can properly track when a user write faults on a previously cleaned address. They also...

View Article[PATCH v2 02/11] mm: add pmd_mkclean()
