ext4: get rid of EXT4_MAP_UNINIT flag
Currently EXT4_MAP_UNINIT is used in dioread_nolock case to mark the cases where we're using dioread_nolock and we're writing into either unallocated, or unwritten extent, because we need to make sure that any DIO write into that inode will wait for the extent conversion. However EXT4_MAP_UNINIT is not only entirely misleading name but also unnecessary because we can check for EXT4_MAP_UNWRITTEN in the dioread_nolock case instead. This commit removes EXT4_MAP_UNINIT flag. Signed-off-by: Lukas Czerner <lczerner@redhat.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
