[patch 0/5] futex: Plug a pi_state leak and clarify the refcounting

Show all headers | View raw

A recent patch claimed that there is a double free in the requeue_pi
code, which is not the case.

While analysing the issue I found the contrary, i.e. a leak. This
series fixes the leak and clarifies the code so it's more clear how
that refcounting on the pi state works.

Thanks,

	tglx
