Re: [PATCH 3/3] iomap: rework IOMAP atomic flags

So, I guess we can shift IOMAP_F_SIZE_CHANGED and IOMAP_F_STALE by
1 bit. So it will all look like..

Let's create some more space to avoid this for the next round, e.g.

Sure, that make sense.

count the core set flags from 31 down, and limit IOMAP_F_PRIVATE to a
single flag, which is how it is used.

flags in struct iomap is of type u16. So will make core iomap flags
starting from bit 15, moving downwards.

Here is a diff of what I think you meant - let me know if this diff
looks good to you?

This is still outstanding, and it would be nice to fix this ASAP.

How about we go to 32b and change IOMAP_F_PRIVATE for v6.16, while just fix as suggested originally (by renumbering) for v6.15?
