Subject: [PATCH] Recognise NVME devices (#755022)
|
||||
|
||||
Add a pattern to recognise Non-Volatile Memory Express devices as valid
|
||||
devices to work with. Devices are named by the Linux kernel device
|
||||
driver like /dev/nvme0n1 [1] with partitions named like /dev/nvme0n1p1
|
||||
[2].
|
||||
|
||||
[1] linux 3.3 drivers/block/nvme.c nvme_alloc_ns()
|
||||
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/drivers/block/nvme.c?id=v3.3#n1351
|
||||
|
||||
[2] Contents of /proc/partitions for a partitioned NVME device
|
||||
$ grep nvme /proc/partitions
|
||||
259 0 390711384 nvme0n1
|
||||
259 1 977 nvme0n1p1
|
||||
259 2 31250000 nvme0n1p2
|
||||
259 3 328209496 nvme0n1p3
|
||||
259 4 31249408 nvme0n1p4
|
||||
|
||||
Bug 755022 - gparted doesn't recognize nvme devices
