Kevin Wolf 35b7f4abd5 block: Add BDRV_O_NO_SHARE for blk_new_open() ... Normally, blk_new_open() just shares all permissions. This was fine originally when permissions only protected against uses in the same process because no other part of the code would actually get to access the block nodes opened with blk_new_open(). However, since we use it for file locking now, unsharing permissions becomes desirable. Add a new BDRV_O_NO_SHARE flag that is used in blk_new_open() to unshare any permissions that can be unshared.
