NAME

SYNOPSIS

9       int journal_dirty_metadata(handle_t * handle, struct buffer_head * bh);
10

ARGUMENTS

12       handle
13           transaction to add buffer to.
14
15       bh
16           buffer to mark
17

DESCRIPTION

19       Mark dirty metadata which needs to be journaled as part of the current
20       transaction.
21
22       The buffer is placed on the transaction's metadata list and is marked
23       as belonging to the transaction.
24
25       Returns error number or 0 on success.
26
27       Special care needs to be taken if the buffer already belongs to the
28       current committing transaction (in which case we should have frozen
29       data present for that commit). In that case, we don't relink the
30

BUFFER

32       that only gets done when the old transaction finally completes its
33       commit.
