The patch titled
fuse: fix compile without CONFIG_BLOCK
has been removed from the -mm tree. Its filename was
fuse-fix-compile-without-config_block.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: fuse: fix compile without CONFIG_BLOCK
From: Miklos Szeredi <miklos@xxxxxxxxxx>
Randy Dunlap wote:
> Should FUSE depend on BLOCK? Without that and with BLOCK=n, I get:
>
> inode.c:(.text+0x3acc5): undefined reference to `sb_set_blocksize'
> inode.c:(.text+0x3a393): undefined reference to `get_sb_bdev'
> fs/built-in.o:(.data+0xd718): undefined reference to `kill_block_super
Most fuse filesystems work fine without block device support, so I
think a better solution is to disable the 'fuseblk' filesystem type if
BLOCK=n.
