-Subject: [PATCH] libvhost-user: Fix the VHOST_USER_PROTOCOL_F_SLAVE_SEND_FD
- check
-
-Vhost user protocol features are set as a bitmask. And the following
-constant VHOST_USER_PROTOCOL_F_SLAVE_SEND_FD value is 10 because the bit
-10 indicates if the features is set or not.
-
-The proper way to check for the presence or absence of this feature is
-to shift 1 by the value of this constant and then mask it with the
-actual bitmask representing the supported protocol features.
-
-This patch aims to fix the current code as it was not doing the
-shifting, but instead it was masking directly with the value of the
-constant itself.
