OCFS2 and direct-io writes
...y?
Would it easier if the data blocks had already been allocated as unwritten extents (using RESVSP)?
I actually attempted to hack the OCFS2 code a bit to allow direct-io writes to happen when the extents
had previously been allocated with a RESVSP. It only to a couple of minor changes:
file.c:ocfs2_prepare_inode_for_write()
Don't disable direct_io if file is growing.
file.c:ocfs2_check_range_for_holes()
Don't treat unwritten extents as holes.
aops.c:ocfs2_direct_IO_get_blocks()
Map unwritten extents if they exists.
With these changes, a single/local OCFS2 filesystem will allow me to wr...

[PATCH 1/2] Ocfs2: Add a mount option "coherency=*" for O_DIRECT writes.
Currently, default behavior of O_DIRECT writes was allowing
concurrent writing among nodes, no cluster coherency guaranteed
(no EX locks was taken), it hurts buffered reads on other nodes
by reading stale data from cache.
The new mount option introduce a chance to choose two different
behaviors for O_DIRECT writes:
* coherency=full, as the default value, will disallow
