Files that consist of an inline extent, have the corresponding
data in the filesystem btree and not on a dedicated extent. For
such extents filefrag (fiemap) will report a physical location
of 0 for that extent and set the 'inline' flag.
The btrfs inspect-internal logical-resolve command will caus
If the file consists of a single block, then filefrag mentions
'1 block of ...', and the filter expected 'blocks of ...'.
Example:
$ echo qwerty > foobar
$ filefrag -v foobar
Filesystem type is: ef53
File size of foobar is 7 (1 block of 4096 bytes)
ext: logical_offset:physical_offset
