[please note that I'm not subscribed to the list] Hi again, this patch adds support for the NILFS2 (http://www.nilfs.org/) filesystem to fstype (on top of 1.5.7 from the debian package). Please let me know what you think. (please note that I'm not affiliated to nilfs in any way). diff -Nur klibc-1.5.7.orig/usr/kinit/fstype/fstype.c klibc-1.5.7/usr/kinit/fstype/fstype.c --- klibc-1.5.7.orig...

...################################################## As can be seen "rsync" has sent about 20M and received 300K of data. However the filesystem has allocated almost 2G, which is the total size of the files being backed up. The filesystem mounted on "/mnt/bkp" is of type "nilfs2", which is a log structured filesystem. I'm using its snapshotting feature to keep backups for past dates. Is there anything that can be done in order "rsync" to overwrite only the changed blocks ? P.S. I guess that it will be the same for copy-on-write filesystems, e.g....

...astly: (8) Compile all of the UAPI headers (with a few exceptions) together as C++ to catch new errors occurring as part of the regular build process. Changes for v2: - Merge commit from sound tree to fix u32 usage issues - Use a switch to fix sparse array initialisation - Simplify nilfs2 by performing bitwise ops in LE space not CPU space - Handle conflicting fix to use of 'private' in keyctl.h - Move kernel internal coda bits to coda internal headers - Move coda_psdev.h header to fs/coda/.

i_alloc_sem has always been a bit of an odd "lock". It''s the only remaining rw_semaphore that can be released by a different thread than the one that locked it, and it''s use case in the core direct I/O code is more like a counter given that the writers already have external serialization. This series removes it in favour of a simpler counter scheme, thus getting rid
