dt: dbx5x0: remove mentor,musb binding

The "mentor,musb" binding isn't documented so I was about
to document it.

The node is missing a few properties for configuration like
"multipoint", "dyn_fifo", "num_eps" or "ram_bits". However
I am not sure "missing" is the right word here because some
of those informations might be obtained from the chip itself
but it is not done (yet).

Further the ePARP 2.3.1 says the matching goes from left to
right taking the fist match. Right now there is jus a driver
for "stericsson,db8500-musb" and none for "mentor,musb".
I'm not 100% that it is simply possible to have a generic
since even for DMA we have ifdefs in the driver between
"generic mentor dma" and "ux500 dma" and I mean within musb
and not the dma code.

For that reason (that I am not sure a generic musb binding
is possible and how its binding / required properties will
look like) and the reason that we have here a minor binding
without a driver to look at I suggest to remove that binding.

If the majority of people prefer to keep this binding I'm
curious how the documentation of the binding should look like.

the whole disk or 2Tib for the pMBR size in LBA.  While most disk
partitioning tools out there create a pMBR with these characteristics,
Microsoft does not, as it always sets the entry to the maximum 32-bit
limitation - even though a drive may be smaller than that[1].

Loosen this check and only verify that the size is either the whole disk
or 0xFFFFFFFF.  No tool in its right mind would set it to any value
other than these.

vfs: fix dentry LRU list handling and nr_dentry_unused accounting

The LRU list changes interacted badly with our nr_dentry_unused
accounting, and even worse with the new DCACHE_LRU_LIST bit logic.

This introduces helper functions to make sure everything follows the
proper dcache d_lru list rules: the dentry cache is complicated by the
fact that some of the hotpaths don't even want to look at the LRU list
at all, and the fact that we use the same list entry in the dentry for
both the LRU list and for our temporary shrinking lists when removing
things from the LRU.

The helper functions temporarily have some extra sanity checking for the
flag bits that have to match the current LRU state of the dentry.  We'll
remove that before the final 3.12 release, but considering how easy it
is to get wrong, this first cleanup version has some very particular
sanity checking.

11 years agocifs: Avoid calling unlock_page() twice in cifs_readpage() when using fscache
Sachin Prabhu [Fri, 13 Sep 2013 13:11:57 +0000 (14:11 +0100)]
cifs: Avoid calling unlock_page() twice in cifs_readpage() when using fscache

When reading a single page with cifs_readpage(), we make a call to
fscache_read_or_alloc_page() which once done, asynchronously calls
the completion function cifs_readpage_from_fscache_complete(). This
completion function unlocks the page once it has been populated from
cache. The module then attempts to unlock the page a second time in
cifs_readpage() which leads to warning messages.

In case of a successful call to fscache_read_or_alloc_page() we should skip
the second unlock_page() since this will be called by the
cifs_readpage_from_fscache_complete() once the page has been populated by
fscache.

With the modifications to cifs_readpage_worker(), we will need to re-grab the
page lock in cifs_write_begin().

The problem was first noticed when testing new fscache patches for cifs.
