...rged. Nevertheless, I hope you can squeeze it into 3.12-rc so we can then start pushing it to stable kernels (at least 3.10). > diff --git a/fs/btrfs/send.c b/fs/btrfs/send.c > index 5445454..4be3832 100644 > --- a/fs/btrfs/send.c > +++ b/fs/btrfs/send.c > @@ -4553,8 +4553,8 @@ long btrfs_ioctl_send(struct file *mnt_file, void __user *arg_) > } > > if (!access_ok(VERIFY_READ, arg->clone_sources, > - sizeof(*arg->clone_sources * > - arg->clone_sources_count))) { > + sizeof(*arg->clone_sources) * > + arg->clone_sources_count)) { > ret = -EF...

First two patches are trivial cleanups that I''ve spotted while reading send.c, can be applied independently. The third patch contains the important bits, safety checks that the subvolumes involved in send do not accidentally lose the RO status. I haven''t seen this documented anywhere that this is mandatory, implied from how I assume send works. Please let me know if this is

Hi everyone, I was trying the new send/receive feature today but can''t make it work. These are the commands I was using: btrfs subvol snap -r /mnt/data1/@downloads/ /mnt/data1/snapshots/testsnap btrfs send /mnt/data1/snapshots/testsnap | btrfs receive /mnt/data1/snapshots/testreceive/ This command never finishes. A ''ls /mnt/data1/snapshots/testreceive/ '' never

Hello, I just updated and pushed btrfs-next, if it is missing something let me know. I had to kick out the printk formatting patch because it didn''t compile and I didn''t take Miao''s background enospc flushing stuff since some of it didn''t apply and 5/5 hasn''t been updated to force waiting on background flushers. Let me know if I missed anything
