help
XFS is a high performance journaling filesystem which originated
on the SGI IRIX platform. It is completely multi-threaded, can
support large files and large filesystems, extended attributes,
variable block sizes, is extent based, and makes extensive use of
Btrees (directories, extents, free space) to aid both performance
and scalability.
Refer to the documentation at
for complete details. This implementation is on-disk compatible
with the IRIX version of XFS.
To compile this file system support as a module, choose M here: the
module will be called xfs. Be aware, however, that if the file
system of your root partition is compiled as a module, you'll need
to use an initial ramdisk (initrd) to boot.
config XFS_QUOTA
bool "XFS Quota support"
depends on XFS_FS
select QUOTACTL
help
If you say Y here, you will be able to set limits for disk usage on
a per user and/or a per group basis under XFS. XFS considers quota
information as filesystem metadata and uses journaling to provide a
higher level guarantee of consistency. The on-disk data format for
quota is also compatible with the IRIX version of XFS, allowing a
filesystem to be migrated between Linux and IRIX without any need
for conversion.
If unsure, say N. More comprehensive documentation can be found in
README.quota in the xfsprogs package. XFS quota can be used either
with or without the generic quota support enabled (CONFIG_QUOTA) -
they are completely independent subsystems.
config XFS_POSIX_ACL
bool "XFS POSIX ACL support"
depends on XFS_FS
select FS_POSIX_ACL
help
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
Linux website .
If you don't know what Access Control Lists are, say N.
config XFS_RT
bool "XFS Realtime subvolume support"
depends on XFS_FS
help
If you say Y here you will be able to mount and use XFS filesystems
which contain a realtime subvolume. The realtime subvolume is a
separate area of disk space where only file data is stored. It was
originally designed to provide deterministic data rates suitable
for media streaming applications, but is also useful as a generic
mechanism for ensuring data and metadata/log I/Os are completely
separated. Regular file I/Os are isolated to a separate device
from all other requests, and this can be done quite transparently
to applications via the inherit-realtime directory inode flag.
See the xfs man page in section 5 for additional information.
If unsure, say N.
config XFS_WARN
bool "XFS Verbose Warnings"
depends on XFS_FS && !XFS_DEBUG
help
Say Y here to get an XFS build with many additional warnings.
It converts ASSERT checks to WARN, so will log any out-of-bounds
conditions that occur that would otherwise be missed. It is much
lighter weight than XFS_DEBUG and does not modify algorithms and will
not cause the kernel to panic on non-fatal errors.
However, similar to XFS_DEBUG, it is only advisable to use this if you
are debugging a particular problem.
config XFS_DEBUG
bool "XFS Debugging support"
depends on XFS_FS
help
Say Y here to get an XFS build with many debugging features,
including ASSERT checks, function wrappers around macros,
and extra sanity-checking functions in various code paths.
Note that the resulting code will be HUGE and SLOW, and probably
not useful unless you are debugging a particular problem.
Say N unless you are an XFS developer, or you play one on TV.

Since the commit b0ca2a21f769 ("sh_eth: Add support of SH7763 to sh_eth")
the *enum* declaring the EESIPR bits (interrupt mask) went out of sync with
the *enum* declaring the EESR bits (interrupt status) WRT bit naming and
formatting. I'd like to restore the consistency by using EESIPR as the bit
name prefix, renaming the *enum* to EESIPR_BIT, and (finally) renaming the
bits according to the available Renesas SH77{34|63} manuals; additionally,
reconstruct couple names using the EESR bit declaration above...
