Make reiserfs3 return f_fsid info for statfs(2). By Andreas' suggestion,
this patch populates a persistent f_fsid between boots/mounts with help of
on-disk uuid record.
Randy Dunlap reported a compiling error from v2 patch like:
fs/built-in.o: In function `reiserfs_statfs':
super.c:(.text+0x7332b): undefined reference to `crc32_le'
super.c:(.text+0x7333f): undefined reference to `crc32_le'
Also he provided helpful solution to fix this error. The modification of v3
patch is based on Randy's suggestion, add 'select CRC32' in fs/reiserfs/Kconfig.

Stores not just filenames but the files themselves in a balanced

tree. Uses journalling.
|
|
|
|
Balanced trees are more efficient than traditional file system
|
|
architectural foundations.
|
|
|
|
In general, ReiserFS is as fast as ext2, but is very efficient with
|
|
large directories and small files. Additional patches are needed
|
|
for NFS and quotas, please see <http://www.namesys.com/> for links.

It is more easily extended to have features currently found in
|
|
database and keyword search systems than block allocation based file
|
|
systems are. The next version will be so extended, and will support
|
|
plugins consistent with our motto ``It takes more than a license to
|
|
make source code open.''

If you set this to Y, then ReiserFS will perform every check it can
|
|
possibly imagine of its internal consistency throughout its
|
|
operation. It will also go substantially slower. More than once we
|
|
have forgotten that this was on, and then gone despondent over the
|
|
latest benchmarks.:-) Use of this option allows our team to go all
|
|
out in checking for consistency when debugging without fear of its
|
|
effect on end users. If you are on the verge of sending in a bug
|
|
report, say Y and you might get a useful error message. Almost

everyone should say N.
