fs: add CONFIG_BUFFER_HEAD Add a new config option that controls building the buffer_head code, and select it from all file systems and stacking drivers that need it. For the block device nodes and alternative iomap based buffered I/O path is provided when buffer_head support is not enabled, and iomap needs a a small tweak to define the IOMAP_F_BUFFER_HEAD flag to 0 to not call into the buffer_head code when it doesn't exist. Otherwise this is just Kconfig and ifdef changes.

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.

support inode time stamps beyond 03:14:07 UTC on 19 January 2038.

Ext2 users are advised to use ext4 driver to access their filesystem.
The driver is fully compatible, supports filesystems without journal
or extents, and also supports larger time stamps if the filesystem
is created with at least 256 byte inodes.
This code is kept as a simple reference for filesystem developers.
If unsure, say N.

Extended attributes are name:value pairs associated with inodes by
fs/*/Kconfig: drop links to 404-compliant http://acl.bestbits.at This link is replicated in most filesystems' config stanzas. Referring to an archived version of that site is pointless as it mostly deals with patches; user documentation is available elsewhere.

Security labels support alternative access control models

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.
