[PATCH] kmemleak: Annotate false positive in init_section_page_cgroup()
The pointer to the page_cgroup table allocated in init_section_page_cgroup() is stored in section->page_cgroup as (base - pfn). Since this value does not point to the beginning or inside the allocated memory block, kmemleak reports a false positive.

Drop dentry reference count when mknod fails
Quoting Tvrtko Ursulin (tvrtko.ursulin(a)sophos.com): lookup_one_len increments dentry reference count which is not decremented when the create operation fails. This can cause a kernel BUG at fs/dcache.c:676 at unmount time. Also error code returned when new_inode() fails was replaced with more appropriat... 15 Jul 2010 22:00

[PATCH 3/5] GFS2: Fix kernel NULL pointer dereference by dlm_astd
From: Bob Peterson <rpeterso(a)redhat.com> This patch fixes a problem in an error path when looking up dinodes. There are two sister-functions, gfs2_inode_lookup and gfs2_process_unlinked_inode. Both functions acquire and hold the i_iopen glock for the dinode being looked up. The last thing they try to do is hol... 15 Jul 2010 10:57

[PATCH 2/5] GFS2: recovery stuck on transaction lock
From: Bob Peterson <rpeterso(a)redhat.com> This patch fixes bugzilla bug #590878: GFS2: recovery stuck on transaction lock. We set the frozen flag on the glock when we receive a completion that cannot be delivered due to blocked locks. At that point we check to see whether the first waiting holder has the noexp f... 15 Jul 2010 10:57

[PATCH 4/5] GFS2: BUG in gfs2_adjust_quota
From: Abhijith Das <adas(a)redhat.com> HighMem pages on i686 do not get mapped to the buffer_heads and this was causing a NULL pointer dereference when we were trying to memset page buffers to zero. We now use zero_user() that kmaps the page and directly manipulates page data. This patch also fixes a boundary cond... 15 Jul 2010 10:57

[PATCH 5/5] GFS2: rename causes kernel Oops
From: Bob Peterson <rpeterso(a)redhat.com> This patch fixes a kernel Oops in the GFS2 rename code. The problem was in the way the gfs2 directory code was trying to re-use sentinel directory entries. In the failing case, gfs2's rename function was renaming a file to another name that had the same non-trivial le... 15 Jul 2010 10:57

EXPORT_SYMBOL set_irq_noprobe, set_irq_chip_and_handler, irq_to_desc ?
We added some irq_chip functionality to the ADP5588 GPIO driver. I wonder whether these symbol should be better exported or not? ERROR: "set_irq_noprobe" [drivers/gpio/adp5588-gpio.ko] undefined!
