any progress on this patch series?

I'm sorry I got distracted at the end of year and did not finish the
series.

I never saw an updated version of this patch series after the last round of
reviews, but it would be great to move it forward.  I have filefrag patches
in my e2fsprogs tree waiting for an updated version of your patch.

I recall the main changes were:
- add FIEMAP_EXTENT_PHYS_LENGTH flag to indicate if fe_phys_length was valid

fe_phys_length will be always valid, so other the flags are set only if it's
not equal to the logical length.

- rename fe_length to fe_logi_length and #define fe_length fe_logi_length
- always fill in fe_phys_length (= fe_logi_length for uncompressed files)
  and set FIEMAP_EXTENT_PHYS_LENGTH whether the extent is compressed or not

This is my understanding and contradicts the first point.

- add WARN_ONCE() in fiemap_fill_next_extent() as described below

I don't know if there was any clear statement about whether there should be
separate FIEMAP_EXTENT_PHYS_LENGTH and FIEMAP_EXTENT_DATA_COMPRESSED flags,
or if the latter should be implicit?  Probably makes sense to have separate
flags.  It should be fine to use:

#define FIEMAP_EXTENT_PHYS_LENGTH	0x00000010

since this flag was never used.

I've kept only FIEMAP_EXTENT_DATA_COMPRESSED, I don't see a need for
FIEMAP_EXTENT_PHYS_LENGTH and this would be yet another flag because the
FIEMAP_EXTENT_DATA_ENCODED is also implied.

I'll send V4, we can discuss the PHYS_LENGTH flag then.
