[Xen-devel] [PATCH v4 0/5] Return failure on failure for more xl commands

Return failure when the command failed for more xl commands:
- mem-set
- cd-insert
- pci-*

This makes xl more useful for scripting.

In the case of mem-set, it means first cleaning up
libxl_set_memory_target() to return useful error codes.

Changes in v4:
- Remove block-attach patch
- Split out removal of spurious getinfolist to a separate patch
- Try to follow CODING_STYLE more closely:
 - In general, don't initialize rc / r, but use set-and-goto
 - Use 'r' for non-libxl error codes
 - Use EXIT_FAILURE and EXIT_SUCCESS rather than magic constants
