Add a new LEGACY_DIRECT_IO config symbol that is only selected by the file systems that still use the legacy blockdev_direct_IO code, so that kernels without support for those file systems don't need to build the code.

help
|
|
Windows implementation of ntfs.sys uses 32 bits per clusters.
|
|
If activated 64 bits per clusters you will be able to use 4k cluster
|
|
for 16T+ volumes. Windows will not be able to mount such volumes.
|

|
|
It is recommended to say N here.

|
|
In Windows 10 one can use command "compact" to compress any files.
|
|
4 possible variants of compression are: xpress4k, xpress8k, xpress16k and lzx.
|
|
If activated you will be able to read such files correctly.

POSIX Access Control Lists (ACLs) support additional access rights
|
|
for users and groups beyond the standard owner/group/world scheme,
|
|
and this option selects support for ACLs specifically for ntfs
|
|
filesystems.
|
|
NOTE: this is linux only feature. Windows will ignore these ACLs.
|
|
|
|
If you don't know what Access Control Lists are, say N.
