Hi, Linus et al,
I've attached a patch which appears to restore O_SYNC capabilities in the
kernel. It's against the fs/buffer.c file. During a __block_commit_write
call, it checks the flags of the file (an extra variable is sent in for
the flag). If O_SYNC is set, then it places the blocks into a bufferlist
and calls ll_rw_block() in due course.
But, don't take my word for it. Try it out yourselves! :-)
