Description

I'm not able to reproduce this on fuse, but with the libcephfs client, the following:

mkdir dir1
cd dir1
create foo
link foo hardlinkfoo
unlink foo
unmount

causes a segfault, see the attached files for a stacktrace and client log.

Proposed fix in wip-3367. The Client::link() call was calling put_inode(dir) on successful completion, instead of leaving the parent directory inode reference incremented.
