10 years agomd: Don't try to set an array to 'read-auto' if it is already in that state.
NeilBrown [Mon, 13 Oct 2008 00:55:12 +0000]
md: Don't try to set an array to 'read-auto' if it is already in that state.

'read-auto' is a variant of 'readonly' which will switch to writable
on the first write attempt.

Calling do_md_stop to set the array readonly when it is already readonly
returns an error.  So make sure not to do that.

10 years agomd: Allow metadata_version to be updated for externally managed metadata.
NeilBrown [Mon, 13 Oct 2008 00:55:11 +0000]
md: Allow metadata_version to be updated for externally managed metadata.

For externally managed metadata, the 'metadata_version' sysfs
attribute is really just a channel for user-space programs to
communicate about how the array is being managed.
It can be useful for this to be changed while the array is active.

Normally changes to metadata_version are not permitted while the array
is active.  Change that so that if the metadata is externally managed,
the metadata_version can be changed to a different flavour of external
management.

10 years agomd: Fix rdev_size_store with size == 0
Chris Webb [Mon, 13 Oct 2008 00:55:11 +0000]
md: Fix rdev_size_store with size == 0

Fix rdev_size_store with size == 0.
size == 0 means to use the largest size allowed by the
underlying device and is used when modifying an active array.

This fixes a regression introduced by
 commit d7027458d68b2f1752a28016dcf2ffd0a7e8f567

10 years agosecurity: avoid calling a NULL function pointer in drivers/video/tvaudio.c

security: avoid calling a NULL function pointer in drivers/video/tvaudio.c

NULL function pointers are very bad security wise. This one got caught by
kerneloops.org quite a few times, so it's happening in the field....

Fix is simple, check the function pointer for NULL, like 6 other places
in the same function are already doing.

MIPS: TXx9: Cache fixup

TX39/TX49 can enable/disable I/D cache at runtime.  Add kernel options
to control them.  This is useful to debug some cache-related issues,
such as aliasing or I/D coherency.  Also enable CWF bit for TX49 SoCs.

r8169: shuffle some registers handling around (8168 operation only)

I can not argue strongly for (or against) a specific ordering
on a purely technical ground but the patch avoids to swallow
Realtek's changes in one big, hard-to-read gulp.

Let aside the way the RxConfig register is written (see
rtl_set_rx_tx_config_registers / RxConfig / rtl_set_rx_mode),
this change brings the registers write ordering closer with
Realtek's driver one (version 8.006.00) for the 8168 chipsets.

More 8168 specific code which touches the Configx registers will
be added in the section covered by Cfg9346_UnLock / Cfg9346_Lock.
