Hello.
Can anyone think of a simple way to copy a set of pages from a given file
(which may or may not be scattered throughout multiple extents) from a snapshot
to correct pages within another file on another snapshot?
This might sound silly, but the whole purpose is to create some sort of

Nack, please fix btrfs_lookup_dentry to return ERR_PTR(-ENOENT) if it
doesn't find something.

Hi Chris,
I think this is patch should go into -rc6 series, it fixes a user-visible bug.
I was confused when I did not see the inode_cache in mount output although I
was sure (and verified in my script) that I had passed it to mount.
thanks,

There are three missed
This just gets us ready to support the SEEK_HOLE and SEEK_DATA flags. Turns out
using fiemap in things like cp cause more problems than it solves, so lets try
and give userspace an interface that doesn't suck. We need to match solaris

Since Ext4 has its own lseek we need to make sure it handles
SEEK_HOLE/SEEK_DATA. For now just do the same thing that is done in the generic
case, somebody else can come along and make it do fancy things later. Thanks,

In order to handle SEEK_HOLE/SEEK_DATA we need to implement our own llseek.
Basically for the normal SEEK_*'s we will just defer to the generic helper, and
for SEEK_HOLE/SEEK_DATA we will use our fiemap helper to figure out the nearest
hole or data. Currently this helper doesn't check for delalloc
This converts everybody to handle SEEK_HOLE/SEEK_DATA properly. In some cases
we just return -EINVAL, in others we do the normal generic thing, and in others
we're simply making sure that the properly due-dilligence is done. For example
in NFS/CIFS we need to make sure the file size is update pro
This is a test to make sure seek_data/seek_hole is acting like it does on
Solaris. It will check to see if the fs supports finding a hole or not and will
adjust as necessary.

Earlier I tried the read only patch with no result. Josef said I must be
applying it wrong because the error I get is not possible with the patch
applied.

Thanks for the reply. copied the patch from the line "diff" onward
did a fresh kernel tree and got the following (same on 2.6.39-r1 and r2)
localhost linux# patch -p1 --dry-run --verbose < disk-io.patch
Hmm... Looks like a unified diff to me...

Attached is a patch to fix a cross compilation issue I observed with
btrfs-tools.

Instead, have it pass those errors back to the callers. Most callers right
now actually BUG_ON the return code anyway so behavior hasn't really changed
in those cases. Others (such as btrfs_sync_log()) try to handle the error
returned. btrfs_ioctl_subvol_setflags() ignores the error today. In order

The return value of btrfs_lookup_dentry is checked so that
the panic such as illegal address reference should not occur.
