Cover letter [RFC/PATCH 0/5] add execute in place support
Folks,
this is the intro to a small series of patches that introduce execute in place into the I/O stack. File I/O to memory-backed block devices is performed directly, bypassing the page cache and io schedulers. On s390, we use this for block devices based on shared memory between multiple virtual machines. This is also useful on embedded systems where the block device is located on a flash chip. This work is a result of a prior discussion with Andrew Morton about my first implementation which basically was a filesystem derived from ext2.
As I'd like to aim for integration into -mm and vanilla later on, I'd like to encourage everyone to give it a read and provide feedback. All patches apply against git-head as of today.
cheers,
Carsten
