Late reply. This one got lost in the flurry of activity...

Originally, multi devices are scanned one by one;
Now, one thread is used per device to scan.

If no chunks need to be recovered, skip the recover works,
meanwhile the user won't be annoyed by the "ask_user".

Decide the raid0/5/6 data stripes' order using checksums.
For one chunk, fetch each 64k logical stripe
1. search its checksum in the csum tree
2. read the physical stripe data on each device
3. calc the data checksums
4. if one checksum matches the value from the csu

Btrfs: remove ourselves from the cluster list under lock
Hi list -
Long time ZFS guy here trying to move everything over from ZFS to btrfs,
which entails a lot of re-scripting and re-learning.
Question of the day: how can I determine the size of a btrfs send
operation before hand? I'd like to be able to provide a progress bar
(I'm accustomed to u
getmntent should be used in context of *mntent functions, though
fopen/fclose works.

btrfs_scan_kernel() does a getmntent() but never releases the
filedescriptor it gets back from that.

Hi
BTRFS filesystem is incompatible with architectures such as PowerPC
and MIPS which have a page size larger than 4k, Meaning that using a
formatted FS on machine with 64K page size will not be mounted on a
machine with 4K page.
I have noticed this remark in the wiki:
https://btrfs.wiki.kernel.o
Now we set @refs to 2 on creating a new extent buffer, meanwhile we
allocate the needed free space, but we don't give enough free_extent_buffer()
to reduce the eb's references to zero so that the eb can finally be freed,
so the problem is we has decrease the referene count of backrefs to zero, whic
We were accounting for sizeof(struct btrfs_item) twice, once
in the data_size variable and another time in the if statement
below.

When allocating chunk root node, we should use nodesize rather than sectorsize,
this will casue regression when making other nodesize choice.(for example 16k
size now)
