Hi Matthew,
I'm not sure what you are trying to achive. Couldn't you simply do
another snapshot of the subvolume? I don't understand why you want to
use send/receive on the same subvolume to be honest.
Regards,
Felix

Btrfs would fail to send if snapshot run concurrently, this test is to make
sure we have fixed the bug.

Hi,
since Freenode is doomed today, i ask the direct way.
Following Filesystem:
Label: 'data' uuid: 3a6fd6d7-5943-4cad-b56f-2e6dcabff453
Total devices 6 FS bytes used 7.02TiB
devid1 size 1.82TiB used 1.82TiB path /dev/sda3
devid2 size 2.73TiB used 2.48TiB path
Btrfs incremental send had an issue where it would detect a non-existent
file hole and then overwrite the file section that hole covers with zeroes,
overriding file data that it shouldn't.
The respective btrfs kernel patch that fixed this issue is titled:
Btrfs: fix send file hole detection
The buffer passed to snprintf can hold the fully expanded format string,
64 = 3x largest ULL + 3x char + trailing null. I don't think that removing the
check entirely is a good idea, hence the ASSERT.

There are only 2 static callers, the BUG would normally be never
reached, but let's be nice.

If cleaning the name cache fails, we could try to proceed at the cost of

This reduces size of the path buffer in common case. Has been tested by
xfstests, but at the moment v3.13 with or without this patch blows, so I'm
sending it anyway.
Based on current btrfs-next/master.

The member is used only to return value back from
fs_path_prepare_for_add, we can do it locally and save 8 bytes for the
inline_buf path.

We know that buf_len is at most PATH_MAX, 4k, and can merge it with the
reversed member. This saves 3 bytes in favor of inline_buf.

The fs_path structure uses an inline buffer and falls back to a chain of
allocations, but vmalloc is not necessary because PATH_MAX fits into
PAGE_SIZE.
The size of fs_path has been reduced to 256 bytes from PAGE_SIZE,
usually 4k. Experimental measurements show that most paths on a single
