Fix barrier fail detection in XFS

Currently we disable barriers as soon as we get a buffer in xlog_iodone
that has the XBF_ORDERED flag cleared.  But this can be the case not only
for buffers where the barrier failed, but also the first buffer of a
split log write in case of a log wraparound.  Due to the disabled
barriers we can easily get directory corruption on unclean shutdowns.
So instead of using this check add a new buffer flag for failed barrier
writes.

This is a regression vs 2.6.26 caused by patch to use the right macro
to check for the ORDERED flag, as we previously got true returned for
every buffer.

Thanks to Toei Rei for reporting the bug.

16 years agoPnP: move pnpacpi/pnpbios_init to after PCI init
Linus Torvalds [Fri, 10 Oct 2008 15:00:17 +0000 (08:00 -0700)]
PnP: move pnpacpi/pnpbios_init to after PCI init

We already did that a long time ago for pnp_system_init, but
pnpacpi_init and pnpbios_init remained as subsys_initcalls, and get
linked into the kernel before the arch-specific routines that finalize
the PCI resources (pci_subsys_init).

This means that the PnP routines would either register their resources
before the PCI layer could, or would be unable to check whether a PCI
resource had already been registered.  Both are problematic.

I wanted to do this before 2.6.27, but every time we change something
like this, something breaks.  That said, _every_ single time we trust
some firmware (like PnP tables) more than we trust the hardware itself
(like PCI probing), the problems have been worse.

dm crypt: avoid unnecessary wait when splitting bio

Don't wait between submitting crypt requests for a bio unless
we are short of memory.

There are two situations when we must split an encrypted bio:
  1) there are no free pages;
  2) the new bio would violate underlying device restrictions
(e.g. max hw segments).

In case (2) we do not need to wait.

Add output variable to crypt_alloc_buffer() to distinguish between
these cases.
