Subject: [PATCH] SMB3: incorrect file id in requests compounded with open
Git-commit: c0d46717b95735b0eacfddbcca9df37a49de9c7a
References: bsc#1190317
Patch-mainline: v5.13-rc3
See MS-SMB2 3.2.4.1.4, file ids in compounded requests should be set to
0xFFFFFFFFFFFFFFFF (we were treating it as u32 not u64 and setting
it incorrectly).
