jbd2_journal_start_reserved — start reserved handle
int jbd2_journal_start_reserved ( | handle_t * handle, |
| unsigned int type, | |
unsigned int line_no); |
Start handle that has been previously reserved with jbd2_journal_reserve.
This attaches handle to the running transaction (or creates one if there's
not transaction running). Unlike jbd2_journal_start this function cannot
block on journal commit, checkpointing, or similar stuff. It can block on
memory allocation or frozen journal though.
Return 0 on success, non-zero on error - handle is freed in that case.
