How do the recent request queue changes influence ll_rw_block()?
Background: i ported LVM but now i immediately get a call to the LVM dummy request function while accessing a logical volume.
This should never happen, because ll_rw_block() calls the LVM remap function (lvm_map) which remaps every i/o to a physical device similar like md does it. In turn this should only queue requests to other devices but not to LVM.
Any hints?
