Name

journal_start — Obtain a new handle.

Synopsis

handle_t * journal_start (journal_t *  journal,
 int  nblocks);

Arguments

journal

Journal to start transaction on.

nblocks

number of block buffer we might modify

Description

We make sure that the transaction can guarantee at least nblocks of modified buffers in the log. We block until the log can guarantee that much space.

This function is visible to journal users (like ext3fs), so is not called with the journal already locked.

Return a pointer to a newly allocated handle, or NULL on failure
