Merge patch series "fs: add i_state helpers"
Christian Brauner <brauner@kernel.org> says:
I've recently looked for some free space in struct inode again because
of some exec kerfuffle we had and while my idea didn't turn into
anything I noticed that we often waste bytes when using wait bit
operations. So I set out to switch that to another mechanism that would
allow us to free up bytes. So this is an attempt to turn i_state from an
unsigned long into an u32 using the individual bytes of i_state as
addresses for the wait var event mechanism (Thanks to Linus for that idea.).
This survives LTP, xfstests on various filesystems, and will-it-scale.
