commit 92c61b5f0b26e643e58320ad4a365ac6d6e23929
Author: Joel Becker <joel.becker at oracle.com>

tunefs.ocfs2: Write out ECC'd blocks and the feature bit.
This finishes the enable_metaecc() functionality. All blocks are
re-written with their CRC/ECC and then the superblock is updated to
support the feature.

commit 2f92829c11d7cde21927b0ee13248f686c575ea3
Author: Joel Becker <joel.becker at oracle.com>
Date: Mon Dec 29 17:27:04 2008 -0800
libocfs2: Add the in-progress flag for enabling dirblock trailers.
When tunefs.ocfs2 is adding directory block trailers, it cannot do it
atomically. For some directory blocks, dirents have to be moved out of
the way to make room for the trailer. These dirents are shifted to new
directory blocks.
When tunefs writes out the changes, it does so in the following order:
1) Write out the new blocks
2) Update the directory's i_size to include the new blocks
3) Write the old blocks with trailers in place.
If tunefs crashes after (1), the new blocks are just unused allocation.
We're safe. If tunefs crashes after (3), we have the directory with
trailers correctly installed. However, if tunefs crashes after (2), the
old dirents are in the old blocks, but the shifted copies are in the new
blocks. This leaves duplicate dirents. fsck.ocfs2 can fix them, but we
need to set OCFS2_TUNEFS_INPROG_DIR_TRAILER to make sure fsck is run.
The alternative order, writing out the old blocks before the new ones,
leaves missing dirents in the case of a crash. That's not a good plan.

tunefs.ocfs2: Start the feature_metaecc program.
The metaecc feature scans all the inodes for any metadata and also scans
for directories that need to have trailers installed. It takes pains to
cache blocks it has seen, because it will need to re-write them with
ecc.
