* [LogFS] Remove h_version fieldJoern Engel2010-03-061-3/+4
| | | | Incompatible change: h_compr is moved up so the padding is all in one chunk.
* [LogFS] Only write journal if dirtyJoern Engel2010-03-041-4/+7
| | | | | This prevents unnecessary journal writes. More importantly it prevents an oops due to a journal write on failed mount.
* [LogFS] Fix bdev erasesJoern Engel2010-03-041-1/+1
| | | | | | | | | | | | Erases for block devices were always just emulated by writing 0xff. Some time back the write was removed and only the page cache was changed to 0xff. Superficialy a good idea with two problems: 1. Touching the page cache isn't necessary either. 2. However, writing out 0xff _is_ necessary for the journal. As the journal is scanned linearly, an old non-overwritten commit entry can be used on next mount and cause havoc. This should fix both aspects.
