sched: Pull up the might_sleep() check into cond_resched()

2009-07-18T13:51:44+00:00

might_sleep() is called late-ish in cond_resched(), after the
need_resched()/preempt enabled/system running tests are
checked.

It's better to check the sleeps while atomic earlier and not
depend on some environment datas that reduce the chances to
detect a problem.

Also define cond_resched_*() helpers as macros, so that the
FILE/LINE reported in the sleeping while atomic warning
displays the real origin and not sched.h

Changes in v2:

 - Call __might_sleep() directly instead of might_sleep() which
   may call cond_resched()

 - Turn cond_resched() into a macro so that the file:line
   couple reported refers to the caller of cond_resched() and
   not __cond_resched() itself.

Changes in v3:

 - Also propagate this __might_sleep() pull up to
   cond_resched_lock() and cond_resched_softirq()

dcache: extrace and use d_unlinked()

2009-06-12T01:36:06+00:00

d_unlinked() will be used in middle-term to ban checkpointing when opened
but unlinked file is detected, and in long term, to detect such situation
and special case on it.

fs: dcache fix LRU ordering

2009-05-09T14:49:40+00:00

Fix ordering of LRU when moving referenced dentries to the head of the list
(they should go to the head of the list in the same order as they were found
from the tail, rather than reverse order).

No need for crossing to mountpoint in audit_tag_tree()

2009-04-21T03:01:15+00:00

is_under() will DTRT anyway.  And yes, is_subdir() behaviour
is intentional.

Get rid of indirect include of fs_struct.h

2009-04-01T03:00:27+00:00

Don't pull it in sched.h; very few files actually need it and those
can include directly.  sched.h itself only needs forward declaration
of struct fs_struct;

cleanup d_add_ci

2009-03-27T18:43:57+00:00

Make sure that comments describe what's going on and not how, and always
use __d_instantiate instead of two separate branches, one with
d_instantiate and one with __d_instantiate.

EXPORT_SYMBOL(d_obtain_alias) rather than EXPORT_SYMBOL_GPL

2009-02-28T00:26:20+00:00

Commit 4ea3ada2955e4519befa98ff55dd62d6dfbd1705 declares d_obtain_alias()
as EXPORT_SYMBOL_GPL where it's supposed to replace d_alloc_anon which was
previously declared as EXPORT_SYMBOL and thus available to any loadable
module.

This patch reverts that.
