[Qemu-devel] [PATCH] configure: Check whether makecontext() is a glibc stub function

On some systems (notably ARM Linux) glibc provides implementations of makecontext(), getcontext() and friends which are stubs which always return failure. Make the configure test for makecontext() also check for the presence of the __stub_makecontext macro which indicates the presence of these stub

[Qemu-devel] [PATCH 3/5] block: Don't call bdrv_eject() if the tray state didn't change
