This is a followup to 'crypto: scompress - eliminate percpu scratch buffers',
which attempted to replace the scompress per-CPU buffer entirely, but as
Herbert pointed out, this is not going to fly in the targeted use cases.
Instead, move the alloc/free of the buffers into the tfm init/exit hooks,
so that we only have the per-CPU buffers allocated if their are any
acomp ciphers of the right kind (i.e, ones that encapsulate a synchronous
implementation) in use (#3)
Patches #1 and #2 are fixes for issues I spotted when working on this code.
Ard Biesheuvel (3):
crypto: scompress - don't sleep with preemption disabled
crypto: scompress - free partially allocated scratch buffers on
failure
crypto: scompress - defer allocation of scratch buffer to first use
