From c7f508a99bf229963915e79a603e0618d1d2ba76 Mon Sep 17 00:00:00 2001 From: Steve French Date: Mon, 14 Oct 2013 15:27:32 -0500 Subject: Allow setting per-file compression via CIFS protocol An earlier patch allowed setting the per-file compression flag "chattr +c filename" on an smb2 or smb3 mount, and also allowed lsattr to return whether a file on a cifs, or smb2/smb3 mount was compressed. This patch extends the ability to set the per-file compression flag to the cifs protocol, which uses a somewhat different IOCTL mechanism than SMB2, although the payload (the flags stored in the compression_state) are the same.
