Back during the Linux 7.0 merge window [1]the MMC changes were rejected by Linus Torvalds as "complete garbage" that wasn't building properly and not vetted through linux-next. He went without pulling any MMC changes for the v7.0 cycle while now for Linux 7.1 the code has been better tested and successfully merged.

The Linux 7.1 MMC changes have landed, including the MMC changes originally intended for Linux 7.0 that were not merged. This includes adding new IDs for NXP WiFi chips over SDIO, support for MMC manufacturing data beyond the year 2025, optimizing support for secure erase/trim on some Kingston eMMCs, support for more Qualcomm hardware in the SDHCI-MSM driver, support for the ASpeed AST2700 in sdhci-of-aspeed, and support for the K3 in the shdci-of-k1. There are also other minor fixes and device ID additions.

The Kingston secure erase work can have quite a dramatic impact in [2]1GB secure erase going from ~10 minutes to about 2 seconds .

The [3]MMC pull request was sent out on Monday and [4]merged on Wednesday without any commentary by Linus Torvalds this cycle.
