ext2, dax: set ext2_dax_aops for dax files
Sync syscall to DAX file needs to flush processor cache, but it currently does not flush to existing DAX files. This is because 'ext2_da_aops' is set to address_space_operations of existing DAX files, instead of 'ext2_dax_aops', since S_DAX flag is set after ext2_set_aops() in the open path. Similar to ext4, change ext2_iget() to initialize i_flags before ext2_set_aops(). Fixes: fb094c90 ("ext2, dax: introduce ext2_dax_aops") Signed-off-by:Toshi Kani <toshi.kani@hpe.com> Suggested-by:
