Linus Torvalds: Linux 2.5.75

Kernel.org
Mirrors

Full
Changelog

Ok. This is it. We (Andrew and me) are going to start a
“pre-2.6” series, where getting patches in is going to be a lot
harder. This is the last 2.5.x kernel, so take note.

The probably most notable thing here is the anticipatory
scheduler, which has been in -mm for a long time, and was the major
piece that hadn’t been merged.

Some architecture updates: cris has been updated for 2.5, ia64
and arm26 updates etc. And various random (smallish) things.

Linus

  proper usage of jiffies.h.

Krzysztof Halasa:

• C99 initializers in hdlc_generic.c

Linus Torvalds:

• The sbp2 driver needs <linux/pci.h>, but didn’t include
  it. It apparently used to work due to some random magic indirect
  include, but broke lately.
• Add an asynchronous buffer read-ahead facility. Nobody uses it
  for now, but I needed it for some tuning tests, and it is
  potentially useful for others.
• Re-organize “ext3_get_inode_loc()” and make it easier to follow
  by splitting it into two functions: one that calculates the
  position, and the other that actually reads the inode block off the
  disk.
• Carl-Daniel Hailfinger suggest adding a paranoid incoming
  trigger as per the “bk help triggers” suggestion, so that we’ll see
  any new triggers showing up in the tree.
• Go back to defaulting to 6-byte commands for MODE SENSE, since
  some drivers seem to be unhappy about the 10-byte version.
• When forcing through a signal for some thread-synchronous event
  (ie SIGSEGV, SIGFPE etc that happens as a result of a trap as
  opposed to an external event), if the signal is blocked we will not
  invoce a signal handler, we will just kill the thread with the
  signal.
• Simplify and speed up mmap read-around handling
• Fix several broken macros to get the “private” field of a
  seq-file in the networking code.
• Avoid deadlocking on thread shutdown after a vfork
• Fix IDE initialization when we don’t probe for interrupts
• Make the gcc version checks use the preprocessor symbols
  consistently.
• Update CREDITS file and other documentation about my new email
  address
• Fix up the IDE irq disable to take into account some
• Fix mailer-induced corruption in initramfs build rules

Matthew Wilcox:

• PCI: Improve documentation Fix some grammar problems Add a note
  about Fast Back to Back support Change the slot_name recommendation
  to pci_name().
• PCI: arch/i386/pci/direct.c can use __init, not __devinit
  pci_sanity_check() is only called from functions marked __init, so
  it can be __init too.
• PCI: pci_findbus needs a domain Give
  pcifind_bus a domain argument and move its declaration to
  <linux/pci.h>
• PCI: Remove pci_busexists Convert all callers
  of pcibus_exists() to call pci_find_bus() instead.
• PCI: arch/i386/pci/irq.c should use pci_findbus Use pcifind_bus rather than relying on the return
  value of pci_scan_bus.
• PCI: arch/i386/pci/legacy.c: use raw_pci_ops Make
  pcibios_fixup_peer_bridges() use raw_pci_ops directly instead of
  faking pci_bus and pci_dev.
• PCI config space in sysfs
• Driver Core: fix firmware binary files Fixes the sysfs binary
  file bug.
• ia64: Use generic pci_scan_bus()
