Description Alexey Shvetsov 2012-10-26 03:31:04 UTC 
In recent kernels like 3.6 ocfs2 hangs on readlink syscall with recent coreutils.
Commit that caused that failure is the following 
commit ea022dfb3c2a4680483b00eb2fecc9fc4f6091d1

    ocfs: simplify symlink handling
    
    seeing that "fast" symlinks still get allocation + copy, we might as
    well simply switch them to pagecache-based variant of ->follow_link();
    just need an appropriate ->readpage() for them...
