[Qemu-devel] [PATCH v3 0/6] Update filename string sizes in block layer

[Jeff Cody]

The block layer uses a mixture of 'PATH_MAX' and '1024' string sizes
for filenames (and backing filenames).

This series consolidates all that usage to 'PATH_MAX'.  Since most platforms
(especially the most common platforms for QEMU) have a PATH_MAX larger than
1024 bytes, this series also changes stack allocations of PATH_MAX to be
dynamically allocated.

Note: checkpatch.pl complains about an extra space in a printf in
      patches 1 & 2.  The lines complained about are in the diff context and
      not the actual changes, so I did not fix them up to satisfy checkpatch.

Changes from v3:
    - simplified extent_path handling in vmdk_parse_extents() (Thanks Stefan)
    - moved declaration of backing_filename2 to inside if
      statement in bdrv_query_image_info() (Thanks Stefan)
    - removed zombie variable in bdrv_commit (Thanks Stefan)
    - fixed typo in commit message (Thanks Stefan)

Changes from v2:

    - Change stack allocations to dybnamic (Thanks Kevin)
    - Update qcow/qcow2 ti perform safety checks for platforms that
      have a PATH_MAX < 1024 (thanks John, Kevin).

Jeff Cody (6):
  block: vmdk - make ret variable usage clear
  block: vmdk - move string allocations from stack to the heap
  block: qapi - move string allocation from stack to the heap
  block: remove unused variable in bdrv_commit
  block: mirror - change string allocation to 2-bytes
  block: update string sizes for filename,backing_file,exact_filename
