xen-blkfront: Drop name and minor adjustments for emulated scsi devices

2011-08-29T20:29:11+00:00

commit 196cfe2ae8fcdc03b3c7d627e7dfe8c0ce7229f9 upstream.

These were intended to avoid the namespace clash when representing
emulated IDE and SCSI devices. However that seems to confuse users
more than expected (a disk defined as sda becomes xvde).
So for now go back to the scheme which does no adjustments. This
will break when mixing IDE and SCSI names in the configuration of
guests but should be by now expected.

xen-blkfront: Introduce BLKIF_OP_FLUSH_DISKCACHE support.

2011-05-12T12:56:03+00:00

If the backend supports the 'feature-flush-cache' mode, use that
instead of the 'feature-barrier' support.

Currently there are three backends that support the 'feature-flush-cache'
mode: NetBSD, Solaris and Linux kernel. The 'flush' option is much
light-weight version than the 'barrier' support so lets try to use as
there are no filesystems in the kernel that use full barriers anymore.

xen-blkfront: fix data size for xenbus_gather in blkfront_connect

2011-05-12T12:55:51+00:00

barrier variable is int, not long. This overflow caused another variable
override: "err" (in PV code) and "binfo" (in xenlinux code -
drivers/xen/blkfront/blkfront.c). The later caused incorrect device
flags (RO/removable etc).

Prepare for extending the block device ring to allow request
specific fields, by moving the request specific fields for
reads, writes and barrier requests to a union member.

xen-blkfront: handle Xen major numbers other than XENVBD

2011-02-25T16:43:05+00:00

This patch makes sure blkfront handles correctly virtual device numbers
corresponding to Xen emulated IDE and SCSI disks: in those cases
blkfront translates the major number to XENVBD and the minor number to a
low xvd minor.

Note: this behaviour is different from what old xenlinux PV guests used
to do: they used to steal an IDE or SCSI major number and use it
instead.
