From 31d4ea1a093fcf668d5f95af44b8d41488bdb7ec Mon Sep 17 00:00:00 2001 From: Vitaly Kuznetsov Date: Fri, 24 Oct 2014 12:20:27 +0200 Subject: [PATCH] Drivers: hv: util: make struct hv_do_fcopy match Hyper-V host messages An attempt to fix fcopy on i586 (bc5a5b0 Drivers: hv: util: Properly pack the data for file copy functionality) led to a regression on x86_64 (and actually didn't fix i586 breakage). Fcopy messages from Hyper-V host come in the following format: struct do_fcopy_hdr | 36 bytes 0000 | 4 bytes offset | 8 bytes size | 4 bytes data | 6144 bytes On x86_64 struct hv_do_fcopy matched this format without ' __attribute__((packed))' and on i586 adding ' __attribute__((packed))' to it doesn't change anything. Keep the structure packed and add padding to match re reality. Tested both i586 and x86_64 on Hyper-V Server 2012 R2. Signed-off-by: Vitaly Kuznetsov Signed-off-by: K. Y.
