This reminds me, we should be checking for a readonly file system up top in
the 'fix' helper.

Also, I'm concerned that the buffer in question might be journaled. In that
case, writing it to disk like this could cause corruptions (if the buffer
contains not-committed changes).

The answer might be to journal the changes we make but I'm not sure if that
can deadlock with other iget() calls.

When the file system becomes read-only, we still can check certain file via it's inode number and report the result (the inode block is integrated or not),
but we cannot fix this file in file system read-only status, otherwise the subsequent logic will become too complex in case we modify/write a inode block under a read-only file system.
Actually, online file check feature should be combined with "errors=continues" option for better using.

I ever though of journaling this changed inode block in case file check fixing, but you know, we are being on inode block loading stage, the journal related structs are not prepared at this moment, then I write this block back to the disk synchronously within ocfs2_inode_lock, it looks a little tricky, but not bring any risk. in case the machine crashes when writing the inode block back to the disk, this will not affect file system integrity, since this inode block original is corrupted, the user can fix this inode block via file check again after the machine is recovered.
Anyway, I just want to let all know what I think behind this part code, maybe it is not right, please give your feedback again.

Thanks
Gang
