i have problems creating more than 39 999 subdirectories in the same
directory in btrfs. i'm using version from kernel 2.6.29 and
mkfs.btrfs 0.18

linux:/t # mount|grep btrfs
/dev/mapper/sys-test on /t type btrfs (rw)
linux:/t # ls|wc -l
31999
linux:/t # mkdir test123
mkdir: cannot create directory `test123': Too many links
linux:/t #

any idea why?
