2010-05-07logfs: handle errors from get_mtd_device()Dan Carpenter1-0/+2
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 Engel1-1/+2
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.
