Btrfs is a new filesystem with extents, writable snapshotting,
|
|
support for multiple devices and many more features.
|
|
|
|
Btrfs is highly experimental, and THE DISK FORMAT IS NOT YET
|
|
FINALIZED. You should say N here unless you are interested in
|
|
testing Btrfs with non-critical data.
|
|
|
|
To compile this file system support as a module, choose M here. The
|
|
module will be called btrfs.
|
|
|
|
If unsure, say N.

POSIX Access Control Lists (ACLs) support permissions for users and

groups beyond the owner/group/world scheme.

To learn more about Access Control Lists, visit the POSIX ACLs for

Adds code that examines all block write requests (including
|
|
writes of the super block). The goal is to verify that the
|
|
state of the filesystem on disk is always consistent, i.e.,
|
|
after a power-loss or kernel panic event the filesystem is
|
|
in a consistent state.
|
|
|
|
If the integrity check tool is included and activated in
|
|
the mount options, plenty of kernel memory is used, and
|
|
plenty of additional CPU cycles are spent. Enabling this
|
|
functionality is not intended for normal use.
|
|
|
|
In most cases, unless you are a btrfs developer who needs
|
|
to verify the integrity of (super)-block write requests
|
|
during the run of a regression test, say N
