There is no longer a dependency on CONFIG_BLOCK in the iomap read and readahead logic. Move this logic out of the CONFIG_BLOCK guard. This allows non-block-based filesystems to use iomap for reads/readahead.Please move the bio code into a new file. Example patch attached below that does just that without addressing any of the previous comments:diff --git a/fs/iomap/Makefile b/fs/iomap/Makefile index f7e1c8534c46..a572b8808524 100644 --- a/fs/iomap/Makefile +++ b/fs/iomap/Makefile@@ -14,5 +14,6 @@ iomap-y += trace.o \ iomap-$(CONFIG_BLOCK) += direct-io.o \ ioend.o \ fiemap.o \ - seek.o + seek.o \ + bio.o iomap-$(CONFIG_SWAP) += swapfile.o
... The version of this for v3 is pretty much exactly what you wrote. i'll add a signed-off-by attributing the patch to you when I send it out. Thanks, Joanne
