(surely not...I'm not that busy, am I?) What is > "executeI in place"? Is the "I" a typo? I did that patch. Since we did have trouble integrating xip2fs (people were not happy with me duplicating part of ext2 code), I did do a shiny new implementation that does'nt have a filesystem anymore: I built execute in place in the generic filemap code [see mm/filemap_xip.c in 2.6.13]. Also, I enabled ext2 to use that (mount option -o xip, see kernel tree 2.6.13 Documentation/filesystems/xip.txt). In order to use it, CONFIG_EXT2_FS_XIP needs to be enabled. There is no specific reason anymore why I chose ext2 different from <me> being too stupid to understand the more complex ext3 journaling code. Also, you can now have execute in place and write support [frankly, not shared-write]- that was impossible with old xip2fs. I am looking forward to replace xip2fs with this cleaner implementation for Sles10 and Rhel5, but I am in no hurry because both the new implementation and the classic xip2fs work fine and I refuse to change usage in a stable distro. In case you want to play with it today, the 2.6.13. version seems to function well out-of-the box. --
