kernel: nvme: add missing SRCU grace period in error path

A flaw was found in the NVMe Non-Volatile Memory Express driver of the Linux kernel. The nvmeallocns function's error handling path fails to wait for all SRCU Sleepable Read-Copy Update readers to complete before freeing a namespace structure. This oversight allows a concurrent reader to access a...

kernel: nvme-pci: fix mempool alloc size

A flaw was addressed in the Linux kernel’s nvme-pci driver related to how the driver calculated the worst-case number of PRP Physical Region Page lists required for a given I/O request. The implementation previously rounded the allocation to one list instead of correctly converting the maximum si...
