There are few important bug fixes for LogFS
* tag 'for-linus' of git://github.com/prasad-joshi/logfs_upstream:
Logfs: Allow NULL block_isbad() methods
logfs: Grow inode in delete path
logfs: Free areas before calling generic_shutdown_super()
logfs: remove useless BUG_ON
MAINTAINERS: Add Prasad Joshi in LogFS maintiners
logfs: Propagate page parameter to __logfs_write_inode
logfs: set superblock shutdown flag after generic sb shutdown
logfs: take write mutex lock during fsync and sync
logfs: Prevent memory corruption
logfs: update page reference count for pined pages
Fix up conflict in fs/logfs/dev_mtd.c due to semantic change in what
"mtd->block_isbad" means in commit f2933e86ad93: "Logfs: Allow NULL
block_isbad() methods" clashing with the abstraction changes in the
commits 7086c19d0742: "mtd: introduce mtd_block_isbad interface" and
d58b27ed58a3: "logfs: do not use 'mtd->block_isbad' directly".
This resolution takes the semantics from commit f2933e86ad, and just
makes mtd_block_isbad() return zero (false) if the 'block_isbad'
function is NULL. But that also means that now "mtd_can_have_bb()"
always returns 0.
Now, "mtd_block_markbad()" will obviously return an error if the
low-level driver doesn't support bad blocks, so this is somewhat
non-symmetric, but it actually makes sense if a NULL "block_isbad"
function is considered to mean "I assume that all my blocks are always
good".
