[Qemu-devel] [PATCH v2 3/4] io: Don't call close multiple times in QIOCh

From: Ross Lagerwall
Subject: [Qemu-devel] [PATCH v2 3/4] io: Don't call close multiple times in QIOChannelFile
Date: Wed, 1 Nov 2017 14:25:25 +0000

If the file descriptor underlying QIOChannelFile is closed in the
io_close() method, don't close it again in the finalize() method since
the file descriptor number may have been reused in the meantime.

Signed-off-by: Ross Lagerwall <address@hidden>
New in v2.
