Merge tag 'for-linus' of git://github.com/prasad-joshi/logfs_upstream
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 f2933e86ad93, 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".
