Chris Mason 1259ab75c6 Btrfs: Handle write errors on raid1 and raid10 ... When duplicate copies exist, writes are allowed to fail to one of those copies. This changeset includes a few changes that allow the FS to continue even when some IOs fail. It also adds verification of the parent generation number for btree blocks. This generation is stored in the pointer to a block, and it ensures that missed writes to are detected. Signed-off-by: Chris Mason <chris.mason@oracle.com>		2008-09-25 11:04:03 -04:00
