Problem Details: This is based upon an excellent bug report from Eric Dumazet. tcp_ack() should clear ->icsk_probes_out even if there are packets outstanding.

Analyze and fix the following issue in the Linux kernel code: mmc_spi: put signals to low power off fix
Problem Details: The original intention was to write a zero byte to mmc to force spi signals to low when doing power off. Somehow the spi_w8r8 call got there so a read followed the write of single zero byte. This patch changes that to simple write of zero byte without the following read. This way the power off is more ...
