2018-11-05drm/amd/display: Retiring set_display_requirements in dm_pp_smu.h - part2Fatemeh Darbehani2-5/+29
[Why] In DCN we want direct DAL to SMU calls, with as little as possible interference by pplib. The reason for each pp_smu interface mapping to 1 SMU message is so we can have the sequencing of different SMU message in dal and shared across different OS. This will also simplify debugging as DAL owns this interaction and there's no confusion about division of ownership.

2018-11-03bfs: add sanity check at bfs_fill_super()Tetsuo Handa1-3/+6
syzbot is reporting too large memory allocation at bfs_fill_super() [1]. Since file system image is corrupted such that bfs_sb->s_start == 0, bfs_fill_super() is trying to allocate 8MB of continuous memory. Fix this by adding a sanity check on bfs_sb->s_start, __GFP_NOWARN and printf().

2018-11-03mm, thp: consolidate THP gfp handling into alloc_hugepage_direct_gfpmaskMichal Hocko5-77/+40
THP allocation mode is quite complex and it depends on the defrag mode. This complexity is hidden in alloc_hugepage_direct_gfpmask from a large part currently. The NUMA special casing (namely __GFP_THISNODE) is however independent and placed in alloc_pages_vma currently. This both adds an unnecessary branch to all vma based page allocation requests and it makes the code more complex unnecessarily as well. Not to mention that e.g. shmem THP used to do the node reclaiming unconditionally regardless of the defrag mode until recently. This was not only unexpected behavior but it was also hardly a good default behavior and I strongly suspect it was just a side effect of the code sharing more than a deliberate decision which suggests that such a layering is wrong. Get rid of the thp special casing from alloc_pages_vma and move the logic to alloc_hugepage_direct_gfpmask. __GFP_THISNODE is applied to the resulting gfp mask only when the direct reclaim is not requested and when there is no explicit numa binding to preserve the current logic. Please note that there's also a slight difference wrt MPOL_BIND now. The previous code would avoid using __GFP_THISNODE if the local node was outside of policy_nodemask(). After this patch __GFP_THISNODE is avoided for all MPOL_BIND policies. So there's a difference that if local node is actually allowed by the bind policy's nodemask, previously __GFP_THISNODE would be added, but now it won't be. From the behavior POV this is still correct because the policy nodemask is used.

2018-11-03ocfs2: fix clusters leak in ocfs2_defrag_extent()Larry Chen1-0/+17
ocfs2_defrag_extent() might leak allocated clusters. When the file system has insufficient space, the number of claimed clusters might be less than the caller wants. If that happens, the original code might directly commit the transaction without returning clusters. This patch is based on code in ocfs2_add_clusters_in_btree().

2018-11-03ocfs2: dlmglue: clean up timestamp handlingArnd Bergmann1-17/+9
The handling of timestamps outside of the 1970..2038 range in the dlm glue is rather inconsistent: on 32-bit architectures, this has always wrapped around to negative timestamps in the 1902..1969 range, while on 64-bit kernels all timestamps are interpreted as positive 34 bit numbers in the 1970..2514 year range. Now that the VFS code handles 64-bit timestamps on all architectures, we can make the behavior more consistent here, and return the same result that we had on 64-bit already, making the file system y2038 safe in the process. Outside of dlmglue, it already uses 64-bit on-disk timestamps anway, so that part is fine. For consistency, I'm changing ocfs2_pack_timespec() to clamp anything outside of the supported range to the minimum and maximum values. This avoids a possible ambiguity of values before 1970 in particular, which used to be interpreted as times at the end of the 2514 range previously.

2018-11-03ocfs2: don't put and assigning null to bh allocated outsideChangwei Ge1-18/+59
ocfs2_read_blocks() and ocfs2_read_blocks_sync() are both used to read several blocks from disk. Currently, the input argument *bhs* can be NULL or NOT. It depends on the caller's behavior. If the function fails in reading blocks from disk, the corresponding bh will be assigned to NULL and put. Obviously, above process for non-NULL input bh is not appropriate. Because the caller doesn't even know its bhs are put and re-assigned. If buffer head is managed by caller, ocfs2_read_blocks and ocfs2_read_blocks_sync() should not evaluate it to NULL. It will cause caller accessing illegal memory, thus crash.
