Re: [PATCH 0/2] optee: fix OOM seen due to tee_shm_free()
The following out of memory errors are seen on kexec reboot from the optee core. [0.368428] tee_bnxt_fw optee-clnt0: tee_shm_alloc failed [0.368461] tee_bnxt_fw: probe of optee-clnt0 failed with error -22 tee_shm_release() is not invoked on dma shm buffer. Implement .shutdown() in optee core as well as bnxt firmware driver to handle the release of the buffers correctly. More info: https://github.com/OP-TEE/optee_os/issues/3637 Jens, Could you please take sometime out and review the series. Thanks.
