Hi all,
I have a Btrfs partition that cannot be mounted anymore, it makes
kernel to crash.
The partition was created a few months ago, with kernel 2.6.33 (with
no special options) if I remember well. Since then, with new kernel
releases, I enabled a few options : first space_cache, then compress,
scrub_page collects several pages into one bio as long as they are physically
contiguous. As we only save one logical address for the whole bio, don't
collect pages that are physically contiguous but logically discontiguous.

If we are looking for a cluster in a particularly sparse or fragmented block
group, we will do a lot of looping through the free space tree looking for
various things, and if we need to look at bitmaps we will endup doing the whole
dance twice. So instead add the bitmap entries to a temporary
When profiling the find cluster code it's hard to tell where we are spending our
time because the bitmap and non-bitmap functions get inlined by the compiler, so
make that not happen. Thanks,

I noticed when running an enospc test that we would get stuck committing the
transaction in check_data_space even though we truly didn't have enough space.
So check to see if bytes_pinned is bigger than num_bytes, if it's not don't
commit the transaction. Thanks,
