[Ocf-linux-users] HELP.

[Nawang C. <naw...@gm...>]

Hi All,
             I browsed through the swcr_newsession code. I realized there is
something seriously wrong.
I am attaching dmesg dump, which clearly indicates where the following bug
message is generated
            BUG: sleeping function called from invalid context at
kernel/rwsem.c:20

I am using OCF with cryptosoft. Basically this result because we take a lock
in cryto_newsession before calling the swcr_newsession. swcr_newsession
further calls a linux crypto library function which is sleeping.
