Subject: [Oracleasm-devel] Compatibility with kernel 3.0+
Message-ID: <2094952.MYFyqGF6Yp@carolin>

Hi,

In order to be compatible with kernels following the addition of longterm 
mount reference counting, the following patch seems needed by oracleasm. 
Without it, the kernel will oops on rmmod (or shutdown, which does an rmmod) 
because the superblock is never removed but the kernel module is, so the 
kernel will oops when it tries to sync all superblocks
