Hi Anand,
Nice work.
But I have some small questions about it.

Hello,
I use OpenSuse 13.2 on my Toshiba Satellite laptop. I noticed that I run
out of disk space, checked documentation and I realized that there were
many snapshots. I used Yast Snapper to delete snapshots.
I noticed that one snapshot with number 748 could not be deleted.
I entered terminal an

Modify the reflink tests to support xfs.

Hi all,
This is part of the third revision of an RFC for adding to XFS support
for tracking reverse-mappings of physical blocks to file and metadata;
and support for mapping multiple file logical blocks to the same
physical block, more commonly known as reflinking.
This patchset aims to make xfst
Hi all,
What am I missing or misunderstanding? I have a newly
purchased laptop I want/need to multi boot different OSs

partitions on each of the two internal drives(sda3, sda8,
sdb3 and sdb8). FWIW, sda3 and sdb3 are the same size

The fdput()s are in the wrong order. fdget(f_in) is first at the beginning, so
fdput(f_in) needs to be last at the end.

Just tested this and can confirm something is off
Hi,
the patch btrfs: properly set the termination value of ctx->pos in
readdir introduces a regression to me.
A lot of stuff runs in "endless" or long running loops.
An example strace looks like this:
