Prasad Joshi eabb26cacd logfs: fix deadlock in logfs_get_wblocks, hold and wait on super->s_write_mutex ... do_logfs_journal_wl_pass() should use GFP_NOFS for memory allocation GC code calls btree_insert32 with GFP_KERNEL while holding a mutex super->s_write_mutex. The same mutex is used in address_space_operations->writepage(), and a call to writepage() could be triggered as a result of memory allocation in btree_insert32, causing a deadlock.
