zcache: Use div_u64 for 64-bit division

2011-08-08T19:05:34+00:00

xv_get_total_size_bytes returns a u64 value and it's used in a division.
This causes build failures in 32-bit architectures, as reported by Randy
Dunlap.

staging:rts_pstor: fix thread synchronization flow

2011-08-08T19:05:34+00:00

Using different completion variables to synchronize different kernel threads

This patch fix a bug that may cause memory leak when driver
disconnected. This is not a very urgent bug. Because with the default
setting, driver disconnectting routine won't be called except when Linux
is shut down. But if the option auto_delink_en is set, a small number of
memory would leak out after memory card unplugged.

staging: zcache: include module.h for MODULE_LICENSE

2011-08-03T14:25:49+00:00

The oncoming cleanup of module.h usage requires the explicit inclusion
of module.h when it was otherwise being included indirectly. Otherwise,
building zcache will fail.

drivers/staging/hv/blkvsc_drv.c: eliminate NULL pointer dereference

2011-08-02T23:12:49+00:00

In this code, blkvsc_req is allocated in the cache blkdev->request_pool,
but freed in the first case to the cache blkvsc_req->dev->request_pool.
blkvsc_req->dev is subsequently initialized to blkdev, making these the
same at the second call to kmem_cache_free.  But at the point of the first
call, blkvsc_req->dev is NULL.  The second call is changed too, for
uniformity.

The semantic patch that fixes this problem is as follows:
(http://coccinelle.lip6.fr/)

// 
@@
expression x,e,e1,e2,e3;
@@

x = \(kmem_cache_alloc\|kmem_cache_zalloc\)(e1,e2)
... when != x = e
(
kmem_cache_free(e1,x);
|
?-kmem_cache_free(e3,x);
+kmem_cache_free(e1,x);
)
