Re: [PATCH 1/4] vfs: vfs-level fiemap interface

Hi,

Just a quick question (not a criticism of the patches in any way):

Is there a specific reason that the flag FIEMAP_EXTENT_DATA_ENCRYPTED exists? I am only asking because there isn't a FIEMAP_EXTENT_DATA_COMPRESSED flag yet the effect on the data is the same. I suppose one could argue that compression is a form of encryption (as one cannot read the data on disk without decompressing it) and thus for compressed files I can just set FIEMAP_EXTENT_DATA_ENCRYPTED, too?

Best regards,

	Anton
