I have made a new version of my small devfs patch against linux-2.5.62.bk4. This version fixes a bug where directory->i_sem was held while devfs_helper ran, which caused deadlock on one system. I am surprised I had not noticed this problem before. This version also adds Documentation/filesystems/devfs/small-devfs, describing differences between the old devfs implementation and this one. You can retrieve the patch from the following URL.
ftp://ftp.yggdrasil.com/pub/dist/device_control/devfs/smalldevfs-2.5.62.4-v11.patch
As before, the optional devfs_helper user level program can be retrived from:
ftp://ftp.yggdrasil.com/pub/dist/device_control/devfs/devfs_helper-0.2.tar.gz
My "to do" list for small devfs is now as follows.
- Submit a patch to the -mm kernels, as Andrew has been kind enough to distribute this change in his -mm kernels. - Remove CONFIG_DEVFS_MOUNT? - Explore eliminating by fs/devfs/fs.c by extending dnotify and ramfs slightly. - Probably request integration after linux-2.7.0.
