NAME

6       journal_forget - bforget for potentially-journaled buffers.
7

SYNOPSIS

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

ARGUMENTS

12       handle
13           transaction handle
14
15       bh
16           bh to 'forget'
17

DESCRIPTION

19       We can only do the bforget if there are no commits pending against the
20       buffer. If the buffer is dirty in the current running transaction we
21       can safely unlink it.
22
23       bh may not be a journalled buffer at all - it may be a non-JBD buffer
24       which came off the hashtable. Check for this.
25
26       Decrements bh->b_count by one.
27
28       Allow this call even if the handle has aborted --- it may be part of
29       the caller's cleanup after an abort.
