-Subject: [PATCH] libparted: Use read only when probing devices on linux
- (#1245144)
-
-When a device is opened for RW closing it can trigger other actions,
-like udev scanning it for partition changes. Use read only for the
-init_* methods and RW for actual changes to the device.
-
-This adds _device_open which takes mode flags as an argument and turns
-linux_open into a wrapper for it with RW_MODE.
-
-_device_open_ro is added to open the device with RD_MODE and increment
-the open_counter. This is used in the init_* functions.
-
-_device_close is a wrapper around linux_close that decrements the
-open_counter and is used in the init_* functions.
-
-All of these changes are self-contained with no external API changes.
-The only visible change in behavior is that when a new PedDevice is
-created the device is opened in RO_MODE instead of RW_MODE.
-
-Resolves: rhbz#1245144
-
-Upstream-Status: Backport
