Pavel Emelyanov cc918897b0 irmap: Introduce irmap on-disk cache ... When dumping fsnotifies we may go to irmap to get inode->path mapping. The irmap engine scans FS (in hinted locations) to get one and it is slow even though we scan only part of the FS. Since the above scanning is done while tasks are frozen the freeze time goes up :( Improve the situation by generating irmap cache in working dir at pre-dump when tasks get unfrozen. The on-disk irmap cache is PB file, it sits in -W directory and can be loaded on dump/pre-dump start in memory. When resolving the inode->path mapping irmap may meet these entries, revalidate them and potentially save time. After pre-dump the (re-)collected irmap data is written back to irmap cache image. Typically entries written back are the same read in on cache load. Signed-off-by: Pavel Emelyanov <xemul@parallels.com>		2014-01-30 16:20:16 +04:00
