Update:
So I have some more patches from trying to support both truncate and
fallocate + punch/insert/collapse for forcealign.
I seem to have at least 2x problems:
- unexpected -ENOSPC in some case
This -ENOSPC seems related to xfs_bmap_select_minlen() again.
I find that it occurs when calling xfs_bmap_select_minlen() and blen ==
maxlen again, like:
blen=64 args->alignment=16, minlen=0, maxlen=64
And then this gives:
args->minlen=48 blen=64
But xfs_alloc_vextent_start_ag() -> xfs_alloc_vextent_iterate_ags() does
not seem to find something suitable.
I'm continuing to look...
