Christoph Hellwig 8b1e7076d2 ext2: use iomap_fiemap to implement ->fiemap
Switch from generic_block_fiemap to use the iomap version.  The only
interesting part is that ext2_get_blocks gets confused when being
asked for overly long ranges, so copy over the limit to the inode
size from generic_block_fiemap into ext2_fiemap.

config EXT2_FS
tristate "Second extended fs support"
select FS_IOMAP
help
Ext2 is a standard Linux file system for hard disks.
To compile this file system support as a module, choose M here: the
module will be called ext2.
If unsure, say Y.
config EXT2_FS_XATTR
bool "Ext2 extended attributes"
depends on EXT2_FS
help
Extended attributes are name:value pairs associated with inodes by
the kernel or by users (see the attr(5) manual page for details).
If unsure, say N.
config EXT2_FS_POSIX_ACL
bool "Ext2 POSIX Access Control Lists"
depends on EXT2_FS_XATTR
select FS_POSIX_ACL
help
Posix Access Control Lists (ACLs) support permissions for users and
groups beyond the owner/group/world scheme.
If you don't know what Access Control Lists are, say N
config EXT2_FS_SECURITY
bool "Ext2 Security Labels"
depends on EXT2_FS_XATTR
help
Security labels support alternative access control models
implemented by security modules like SELinux. This option
enables an extended attribute handler for file security
labels in the ext2 filesystem.
If you are not using a security module that requires using
extended attributes for file security labels, say N.
