| 1 | reiser4 is fully atomic. A transactions happens completely or it doesn't. |
| 2 | |
| 3 | Unlike ext4 or btrfs or xfs. |
| 4 | |
| 5 | reiser4 also uses barriers (the others use them too, but), when barriers are |
| 6 | not available for some reason or another, it complains in dmesg and goes into |
| 7 | sync mode. |
| 8 | |
| 9 | This combined makes it pretty robust against power failures. You won't get the |
| 10 | good old xfs/ext4/btrfs problem that a rename can end with two useless empty |
| 11 | files. |
