> Just curious: what about the rsync+ patch? Thanks for the reminder. I've just committed Jos's rsync+ patch onto the "branch_mbp_rsyncplus_merge" branch. If it works OK and nobody screams I will move it across onto the main tree tomorrow or Wednesday. I see the patch doesn't add documentation about the new options to the man page, so we should fix that in the future.

...anyway. This is not a wholesale conversion which makes kmap_atomic magically preemptible because there might be usage sites which rely on the implicit preempt disable. So this needs to be done on a case by case basis and the call sites converted to kmap_local(). Note, that this is only tested on X86 and completely untested on all other architectures (at least it compiles except on csky which does not compile with the newest cross tools from kernel.org independent of this change). The lot is available from git://git.kernel.org/pub/scm/linux/kernel/git/tglx/devel.git highmem It is based on...
