2010-05-07logfs: handle errors from get_mtd_device()Dan Carpenter
The get_mtd_device() function returns error pointers on failure and if we don't handle it, it leads to a crash. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Joern Engel <joern@logfs.org>
2010-03-04[LogFS] Fix bdev erasesJoern Engel
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.
