Subject[PATCH 0/2] uio: open(), mmap(), close()
Date
After open(), mmap(), close() POSIX 1003.1 mmap() declares the mmaped pointer
valid. Add a warning to the documentation to inform UIO users keep this
behaviour into account.
While the inode parameter of in tree UIO kernel drivers is unused by
open/release hooks, remove teh inode parateter. This would help to process
the release hook in an unmap context.

uio: add warning to documentation
uio: do not expose inode to uio open/release hooks
