> ZFS supports SEEK_HOLE/SEEK_DATA in "lseek()" syscall.

I don't know if this could help, but recently Linux did get some commits regarding SEEK_HOLE/SEEK_DATA ( e.g. http://git.kernel.org/linus/982d816581eeeacfe5b2b7c6d47d13a157616eff ). I haven't tested whether it works / which filesystems support it. Grepping the Linux sources for SEEK_HOLES gives me several hits, e.g. for btrfs. |
