tristate "JFS filesystem support"
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.

select NLS
fs/jfs: Use common ucs2 upper case table Use the UCS-2 upper case tables from nls, that are shared with smb. This code in JFS is hard to test, so we're only reusing the same tables (which are identical), not trying to reuse the rest of the helper functions.

If you do not intend to use the JFS filesystem, say N.
config JFS_POSIX_ACL
bool "JFS POSIX Access Control Lists"
depends on JFS_FS
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 JFS_SECURITY
bool "JFS Security Labels"
depends on JFS_FS
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 jfs filesystem.
If you are not using a security module that requires using
extended attributes for file security labels, say N.
config JFS_DEBUG
bool "JFS debugging"
depends on JFS_FS
help
If you are experiencing any problems with the JFS filesystem, say
Y here. This will result in additional debugging messages to be
written to the system log. Under normal circumstances, this
results in very little overhead.
config JFS_STATISTICS
bool "JFS statistics"
depends on JFS_FS
help
Enabling this option will cause statistics from the JFS file system
to be made available to the user in the /proc/fs/jfs/ directory.
