* | logfs: handle powerfail on NAND flashJoern Engel2010-05-071-0/+2
| | | | | | | | | | | | | | The write buffer may not have been written and may no longer be written due to an interrupted write in the affected page. Signed-off-by: Joern Engel <joern@logfs.org>

* [LogFS] Prevent mempool_destroy NULL pointer dereferenceJoern Engel2010-04-151-0/+6
| | | | | | | | | | | | It would probably be better to just accept NULL pointers in mempool_destroy(). But for the current -rc series let's keep things simple. This patch was lost in the cracks for a while. Kevin Cernekee <cernekee@gmail.com> had to rediscover the problem and send a similar patch because of it. :( Signed-off-by: Joern Engel <joern@logfs.org>
* [LogFS] Prevent memory corruption on large deletesJoern Engel2010-04-131-1/+7
| | | | | | | | | | | | Removing sufficiently large files would create aliases for a large number of segments. This in turn results in a large number of journal entries and an overflow of s_je_array. Cheap fix is to add a BUG_ON, turning memory corruption into something annoying, but less dangerous. Real fix is to count the number of affected segments and prevent the problem completely.

* [LogFS] Remove unused methodJoern Engel2010-03-301-1/+0
| | | | | | All callers are long gone. Signed-off-by: Joern Engel <joern@logfs.org>
* [LogFS] Clear PagePrivate when moving journalJoern Engel2010-03-281-0/+1
| | | | | | | do_logfs_journal_wl_pass() must call freeseg(), thereby clear PagePrivate on all pages of the current journal segment. Signed-off-by: Joern Engel <joern@logfs.org>
* [LogFS] Only write journal if dirtyJoern Engel2010-03-041-2/+2
| | | | | This prevents unnecessary journal writes. More importantly it prevents an oops due to a journal write on failed mount.
* [LogFS] Fix bdev erasesJoern Engel2010-03-041-2/+4
| | | | | | | | | | | | 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.
* [LogFS] add new flash file systemJoern Engel2009-11-201-0/+722
This is a new flash file system. See Documentation/filesystems/logfs.txt Signed-off-by: Joern Engel <joern@logfs.org>
