Subject: [PATCH 3/8] virtiofsd: Changed fuse_pollhandle allocation to GLib's functions
Date: Fri, 19 Mar 2021 15:25:22 +0200	[thread overview]
Message-ID: <20210319132527.3118-4-ma.mandourr@gmail.com> (raw)
In-Reply-To: <20210319132527.3118-1-ma.mandourr@gmail.com>

Changed allocation of fuse_pollhandle structs to GLib's g_new().

Removed the null checking as allocating such a small memory segment
should always succeed on a healthy system. Otherwise, the system
is already in a critical state.
