[PATCH v2 01/10] block: Add a 'flags' param to bdrv_{pread, pwrite, pwrite_sync}() |

Date: |

For consistency with other I/O functions, and in preparation to
implement them using generated_co_wrapper.
Callers were updated using this Coccinelle script:
@@ expression child, offset, buf, bytes; @@
- bdrv_pread(child, offset, buf, bytes)
+ bdrv_pread(child, offset, buf, bytes, 0)
@@ expression child, offset, buf, bytes; @@
- bdrv_pwrite(child, offset, buf, bytes)
+ bdrv_pwrite(child, offset, buf, bytes, 0)
@@ expression child, offset, buf, bytes; @@
- bdrv_pwrite_sync(child, offset, buf, bytes)
+ bdrv_pwrite_sync(child, offset, buf, bytes, 0)
Resulting overly-long lines were then fixed by hand.
