fs/ext2/namei.c: remove unnecessary new_valid_dev() check

2015-11-09T23:11:24+00:00

new_valid_dev() always returns 1, so the !new_valid_dev() check is not
needed.  Remove it.

dax: unify ext2/4_{dax,}_file_operations

2015-04-15T23:35:20+00:00

The original dax patchset split the ext2/4_file_operations because of the
two NULL splice_read/splice_write in the dax case.

In the vfs if splice_read/splice_write are NULL we then call
default_splice_read/write.

What we do here is make generic_file_splice_read aware of IS_DAX() so the
original ext2/4_file_operations can be used as is.

For write it appears that iter_file_splice_write is just fine.  It uses
the regular f_op->write(file,..) or new_sync_write(file, ...).

ext2: get rid of most mentions of XIP in ext2

2015-02-17T01:56:04+00:00

To help people transition, accept the 'xip' mount option (and report it in
/proc/mounts), but print a message encouraging people to switch over to
the 'dax' option.
