Merge branch 'for-linus-4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs
Pull btrfs fixes from Chris Mason: "A few more btrfs fixes. These range from corners Filipe found in the new free space cache writeback to a grab bag of fixes from the list" * 'for-linus-4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs: Btrfs: btrfs_release_extent_buffer_page didn't free pages of dummy extent Btrfs: fill ->last_trans for delayed inode in btrfs_fill_inode. btrfs: unlock i_mutex after attempting to delete subvolume during send btrfs: check io_ctl_prepare_pages return in __btrfs_write_out_cache btrfs: fix race on ENOMEM in alloc_extent_buffer btrfs: handle ENOMEM in btrfs_alloc_tree_block Btrfs: fix find_free_dev_extent() malfunction in case device tree has hole Btrfs: don't check for delalloc_bytes in cache_save_setup Btrfs: fix deadlock when starting writeback of bg caches Btrfs: fix race between start dirty bg cache writeout and bg deletion
