journal_dirty_metada(9)
NAME
journal_dirty_metadata - mark a buffer as containing dirty metadata
SYNOPSIS
int journal_dirty_metadata(handle_t * handle, struct buffer_head * bh);
ARGUMENTS
- handle
- transaction to add buffer to.
- bh
- buffer to mark
DESCRIPTION
Mark dirty metadata which needs to be journaled as part of the current
transaction.
The buffer is placed on the transactionīs metadata list and is marked
as belonging to the transaction.
Returns error number or 0 on success.
Special care needs to be taken if the buffer already belongs to the
current committing transaction (in which case we should have frozen
data present for that commit). In that case, we donīt relink the
BUFFER
that only gets done when the old transaction finally completes its
commit.
