09a80aba8e Rename tty_subr.c' to subr_clist.c'.
Because clists are also used outside the TTY layer, rename the file
containing the clist routines to something more accurate.

The mpsafetty TTY layer doesn't use clists. It uses its own buffers,
which also implement the unbuffered copying to userspace. We cannot
simply remove the clist routines then, because this would break various
drivers that are present within the kernel.

2bc599822b Release pcm mutex before calling snd_clone_unref(), which in turns might
calling destroy_dev() with sleepable malloc(9). The entire opetation
is being serialized through pcm cv from top down, so dropping mutex is
rather safe.

a5ebadc632 Add driver support for PCIe adapters based on JMicron JMC250
gigabit ethernet and JMC260 fast ethernet controllers. ATM jme(4)
supports all hardware features except RSS and multiple Tx/Rx queue.

In these days most ethernet controller vendors take a ply of
concealing hardware detailes from open source developers. As
contrasted with these vendors JMicron provided all necessary
information needed to write a stable driver during driver writing
and answered many questions I had. They even helped fixing driver
bugs with protocol analyzer. Many thanks to JMicron for their
support of FreeBSD.

edf4632700 Once the ENOLCK is detected we expect to retry the acquisition.
Anyway, in the edge case the flushing happens and the while is no more
executed, nfs_flush() (and nfs4_flush()) can return with a wrong
err value of ENOLCK.
Bring it back to 0, as we expect to have for that case.

037dab5792 Use _WANT_FILE to make struct file visible from userland. This is
similar to _WANT_UCRED and _WANT_PRISON and seems to be much nicer than
defining _KERNEL.

2e598474fa Remove ISDN4BSD (I4B) from HEAD as it is not MPSAFE and
parts relied on the now removed NET_NEEDS_GIANT.
Most of I4B has been disconnected from the build
since July 2007 in HEAD/RELENG_7.

This is what was removed:
- configuration in /etc/isdn
- examples
- man pages
- kernel configuration
- sys/i4b (drivers, layers, include files)
- user space tools
- i4b support from ppp
- further documentation

454f3b9249 Dont call ata_start() when ata_reinit fails in the ioctl path. 2008-05-26 08:58:48 +00:00
Xin LI
9f2c7365ab We can not call iwn_start directly in the interrupt
context, where the iwn mutex is being held, and
iwn_start assumes that we do not have that mutex held.

Resolve this issue with what we do for other NICs by
splitting the iwn_start procedure into two parts,
iwn_start() do the locking, and iwn_start_locked()
assumes that the mutex is being held.  This resolves
panic when WITNESS is enabled.

It also introduces the correct usage of memory barriers, as sometimes

ba3042115f To date, our implementation of munmap(2) has required that the
entirety of the specified range be mapped.  Specifically, it has
returned EINVAL if the entire range is not mapped.  There is not,
however, any basis for this in either SuSv2 or our own man page.
Moreover, neither Linux nor Solaris impose this requirement.  This
revision removes this requirement.

60af8a6a7a - Add locking to all filesystem operations in fdescfs and flag it as MPSAFE.
- Use proper synhronization primitives to protect the internal fdesc node cache
  used in fdescfs.
- Properly initialize and uninitalize hash.
- Remove unused functions.

Since fdescfs might recurse on itself, adding proper locking to it needed some
tricky workarounds in some parts to make it work. For instance, a descriptor in
fdescfs could refer to an open descriptor to itself, thus forcing the thread to
recurse on vnode locks. Because of this, other race conditions also had to be
fixed.
