There's no need to retain the fs/autofs4 directory for backward compatibility. Adding an AUTOFS4_FS fragment to the autofs Kconfig and a module alias for autofs4 is sufficient for almost all cases. Not keeping fs/autofs4 remnants will prevent "insmod <path>/autofs4/autofs4.ko" from working but this shouldn't be used in automation scripts rather than modprobe(8). There were some comments about things to look out for with the module rename in the fs/autofs4/Kconfig that is removed by this patch, see the commit patch if you are interested. One potential problem with this change is that when the fs/autofs/Kconfig fragment for AUTOFS4_FS is removed any AUTOFS4_FS entries will be removed from the kernel config, resulting in no autofs file system being built if there is no AUTOFS_FS entry also. This would have also happened if the fs/autofs4 remnants had remained and is most likely to be a problem with automated builds. Please check your build configurations before the removal which will occur after the next couple of kernel releases.

Direct Access (DAX) can be used on memory-backed block devices.

If the block device supports DAX and the filesystem supports DAX,

Tmpfs is a file system which keeps all files in virtual memory.
|
|
|
|
Everything in tmpfs is temporary in the sense that no files will be
|
|
created on your hard drive. The files live in memory and swap
|
|
space. If you unmount a tmpfs instance, everything stored therein is
|
|
lost.

this option as there are a number of Linux distros that require

POSIX ACL support under /dev for certain features to work properly.
