## AI overview

Linux 7.4's merged block updates include fixes spanning legacy floppy hardware and newer Apple storage. The floppy driver received a stack out-of-bounds fix, correction of a regression affecting drive-structure flags, and fixes for data races identified by unspecified tools. The SWIM driver for older Apple Macintosh floppy controllers also received 33 fixes; the changes were tested on four models: Mac Quadra 650, Mac LC III, Mac Quadra 700, and Mac IIvx. On newer hardware, the updates add support for NVMe storage on Apple M4 T8132 ANS2 devices.

## Source excerpt

The Linux 7.4 block/storage and IO_uring updates were merged today for the ongoing merge window. With the breadth of Linux hardware support, the pull request varies from fixes to Linux's floppy driver to enabling support for NVMe storage on Apple M4 devices...
