while using a UFS snapshot.
The UFS filesystem supports snapshots. Each snapshot is a file whose
contents are a frozen image of the disk partition on which the filesystem
resides. Each time an existing block in the filesystem is modified,
the filesystem checks whether that block was in use at the time that
the snapshot was taken. If so, and if it has not already been copied,
a new block is allocated from among the blocks that were not in use
at the time that the snapshot was taken and placed in the snapshot file
to replace the entry that has not yet been copied. The previous contents
of the block are copied to the newly allocated snapshot file block,
and the write to the original is then allowed to proceed.
The block allocation is done using the usual UFS_BALLOC() routine
which allocates the needed block in the snapshot and returns a
buffer that is set up to write data into the newly allocated block.
In usual filesystem operation, the contents for the new block is
copied from user space into the buffer and the buffer is then written
to the file using bwrite(), bawrite(), or bdwrite(). In the case of a
snapshot the new block must be filled from the disk block that is about
to be rewritten. The snapshot routine has a function readblock() that
it uses to read the `about to be rewritten' disk block.
/*
* Read the specified block into the given buffer.
*/
static int
readblock(snapvp, bp, lbn)
struct vnode *snapvp;
struct buf *bp;
ufs2_daddr_t lbn;
{
struct inode *ip;
struct bio *bip;
struct fs *fs;
ip = VTOI(snapvp);
fs = ITOFS(ip);
bip = g_alloc_bio();
bip->bio_cmd = BIO_READ;
bip->bio_offset = dbtob(fsbtodb(fs, blkstofrags(fs, lbn)));
bip->bio_data = bp->b_data;
bip->bio_length = bp->b_bcount;
bip->bio_done = NULL;
g_io_request(bip, ITODEVVP(ip)->v_bufobj.bo_private);
bp->b_error = biowait(bip, "snaprdb");
g_destroy_bio(bip);
return (bp->b_error);
}
When the underlying disk fails, its GEOM module is removed.
Subsequent attempts to access it should return the ENXIO error.
The functionality of checking for the lost disk and returning
ENXIO is handled by the g_vfs_strategy() routine:
void
g_vfs_strategy(struct bufobj *bo, struct buf *bp)
{
struct g_vfs_softc *sc;
struct g_consumer *cp;
struct bio *bip;
cp = bo->bo_private;
sc = cp->geom->softc;
/*
* If the provider has orphaned us, just return ENXIO.
*/
mtx_lock(&sc->sc_mtx);
if (sc->sc_orphaned || sc->sc_enxio_active) {
mtx_unlock(&sc->sc_mtx);
bp->b_error = ENXIO;
bp->b_ioflags |= BIO_ERROR;
bufdone(bp);
return;
}
sc->sc_active++;
mtx_unlock(&sc->sc_mtx);
bip = g_alloc_bio();
bip->bio_cmd = bp->b_iocmd;
bip->bio_offset = bp->b_iooffset;
bip->bio_length = bp->b_bcount;
bdata2bio(bp, bip);
if ((bp->b_flags & B_BARRIER) != 0) {
bip->bio_flags |= BIO_ORDERED;
bp->b_flags &= ~B_BARRIER;
}
if (bp->b_iocmd == BIO_SPEEDUP)
bip->bio_flags |= bp->b_ioflags;
bip->bio_done = g_vfs_done;
bip->bio_caller2 = bp;
g_io_request(bip, cp);
}
Only after checking that the device is present does it construct
the "bio" request and call g_io_request(). When readblock()
constructs its own "bio" request and calls g_io_request() directly
it panics with "consumer not attached in g_io_request" when the
underlying device no longer exists.
The fix is to have readblock() call g_vfs_strategy() rather than
constructing its own "bio" request:
/*
* Read the specified block into the given buffer.
*/
static int
readblock(snapvp, bp, lbn)
struct vnode *snapvp;
struct buf *bp;
ufs2_daddr_t lbn;
{
struct inode *ip;
struct fs *fs;
ip = VTOI(snapvp);
fs = ITOFS(ip);
bp->b_iocmd = BIO_READ;
bp->b_iooffset = dbtob(fsbtodb(fs, blkstofrags(fs, lbn)));
bp->b_iodone = bdone;
g_vfs_strategy(&ITODEVVP(ip)->v_bufobj, bp);
bufwait(bp);
return (bp->b_error);
}
Here it uses the buffer that will eventually be written to the disk.
The g_vfs_strategy() routine uses four parts of the buffer: b_bcount,
b_iocmd, b_iooffset, and b_data.
The b_bcount field is already correctly set for the buffer. It is
safe to set the b_iocmd and b_iooffset fields as they are set
correctly when the later write is done. The write path will also
clear the B_DONE flag that our use of the buffer will set. The
b_iodone callback has to be set to bdone() which will do just
notification that the I/O is done in bufdone(). The rest of
bufdone() includes things like processing the softdeps associated
with the buffer should not be done until the buffer has been
written. Bufdone() will set b_iodone back to NULL after using it,
so the full bufdone() processing will be done when the buffer is
written. The final change from the previous version of readblock()
is that it used the b_data for the destination of the read while
g_vfs_strategy() uses the bdata2bio() function to take advantage
of VMIO when it is available.

In NTB gen3 driver, it was supposed to disable NTB bar access by
default, but due to incorrect register access method, the bar disable
logic does not work as expected. Those registers should be modified
through NTB bar0 rather than PCI configuration space.
Besides, we'd better to protect ourselves from a bad buddy node so

If the default range of [0, ~0] is given, then (~0 - 0) + 1 == 0. This
in turn will cause any allocation of non-zero size to fail. Zero-sized
allocations are prohibited, so add a KASSERT to this effect.

In D21096 BUS_TRANSLATE_RESOURCE was introduced to allow LinuxKPI to get
physical addresses in pci_resource_start for PowerPC and implemented
in ofw_pci.
When the translation was implemented in pci_host_generic in 372c142b4f,
this method was not implemented; instead a local static function was
added for a similar purpose.
Rename the static function to "_common" and implement the bus function
as a wrapper around that. With this a LinuxKPI driver using
physical addresses correctly finds the configuration registers of
the GPU.
This unbreaks amdgpu on NXP Layerscape LX2160A SoC (SolidRun HoneyComb
LX2K workstation) which has a Translation Offset in ACPI for
below-4G PCI addresses.

Drop fpstate only after copying out xfpustate from the thread usermode

returns the pointer directly into user save area, and copyout, would

Commit 5e5ca4c8fc added a flag to a NFSv4 mount point that is set when
the first delegation is acquired from the NFSv4 server.
For a common case where delegations are not being issued by the
NFSv4 server, the nfscl_removedeleg() code acquires the mutex lock for
open/lock state, finds the delegation list empty, then just unlocks the
mutex and returns. This patch adds a check of the flag to avoid the
need to acquire the mutex for this common case.
This change appears to be performance neutral for a small number
of opens, but should reduce lock contention for a large number of opens
for the common case where server is not issuing delegations.
This commit should not affect the high level semantics of delegation
handling.
