* mm: align vmstat_work's timerAnton Blanchard2009-04-031-2/+3
| | | | | | | | | | | Even though vmstat_work is marked deferrable, there are still benefits to aligning it. For certain applications we want to keep OS jitter as low as possible and aligning timers and work so they occur together can reduce their overall impact.

* writeback: guard against jiffies wraparound on inode->dirtied_when checks ↵Jeff Layton2009-04-031-4/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (try #3) The dirtied_when value on an inode is supposed to represent the first time that an inode has one of its pages dirtied. This value is in units of jiffies. It's used in several places in the writeback code to determine when to write out an inode. The problem is that these checks assume that dirtied_when is updated periodically. If an inode is continuously being used for I/O it can be persistently marked as dirty and will continue to age. Once the time compared to is greater than or equal to half the maximum of the jiffies type, the logic of the time_*() macros inverts and the opposite of what is needed is returned. On 32-bit architectures that's just under 25 days (assuming HZ == 1000). As the least-recently dirtied inode, it'll end up being the first one that pdflush will try to write out. sync_sb_inodes does this check: /* Was this inode dirtied after sync_sb_inodes was called? */ if (time_after(inode->dirtied_when, start)) break; ...but now dirtied_when appears to be in the future. sync_sb_inodes bails out without attempting to write any dirty inodes. When this occurs, pdflush will stop writing out inodes for this superblock. Nothing can unwedge it until jiffies moves out of the problematic window. This patch fixes this problem by changing the checks against dirtied_when to also check whether it appears to be in the future. If it does, then we consider the value to be far in the past. This should shrink the problematic window of time to such a small period (30s) as not to matter.

* vfs: skip I_CLEAR state inodesWu Fengguang2009-04-033-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | clear_inode() will switch inode state from I_FREEING to I_CLEAR, and do so _outside_ of inode_lock. So any I_FREEING testing is incomplete without a coupled testing of I_CLEAR. So add I_CLEAR tests to drop_pagecache_sb(), generic_sync_sb_inodes() and add_dquot_ref(). Masayoshi MIZUMA discovered the bug in drop_pagecache_sb() and Jan Kara reminds fixing the other two cases. Masayoshi MIZUMA has a nice panic flow: ===================================================================== [process A] | [process B] | | | prune_icache() | drop_pagecache() | spin_lock(&inode_lock) | drop_pagecache_sb() | inode->i_state |= I_FREEING; | | | spin_unlock(&inode_lock) | V | | | spin_lock(&inode_lock) | V | | | dispose_list() | | | list_del() | | | clear_inode() | | | inode->i_state = I_CLEAR | | | | | V | | | if (inode->i_state & (I_FREEING|I_WILL_FREE)) | | | continue; <==== NOT MATCH | | | | | | (DANGER from here on!

* nommu: fix a number of issues with the per-MM VMA patchDavid Howells2009-04-036-34/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix a number of issues with the per-MM VMA patch: (1) Make mmap_pages_allocated an atomic_long_t, just in case this is used on a NOMMU system with more than 2G pages. Makes no difference on a 32-bit system. (2) Report vma->vm_pgoff * PAGE_SIZE as a 64-bit value, not a 32-bit value, lest it overflow. (3) Move the allocation of the vm_area_struct slab back for fork.c. (4) Use KMEM_CACHE() for both vm_area_struct and vm_region slabs. (5) Use BUG_ON() rather than if () BUG(). (6) Make the default validate_nommu_regions() a static inline rather than a #define. (7) Make free_page_series()'s objection to pages with a refcount != 1 more informative. (8) Adjust the __put_nommu_region() banner comment to indicate that the semaphore must be held for writing. (9) Limit the number of warnings about munmaps of non-mmapped regions.

We want to paravirtualize only __kernel_syscall_via_epc because it includes privileged instructions. Its paravirtualization increases its symbols size. On the other hand, each paravirtualized gate must have e symbols of same value and size to native's because the page is mapped to GATE_ADDR and GATE_ADDR + PERCPU_PAGE_SIZE and vmlinux is linked to those symbols. Later to have the same symbol size, we pads NOPs at the end of __kernel_syscall_via_epc. Move it after other functions to keep symbols of other functions have same values and sizes.

Furthermore, there has been at least one report of a BIOS which assumes that the buffer it is pointed at is the same buffer as for the previous E820 call. Therefore, read the data into a temporary buffer and copy the standard part of it if and only if the valid bit is set. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Impact: BIOS bugproofing Since there are BIOSes known to clobber %ebx and %esi for INT 15 E820, assume there is something out there clobbering %edi and/or %ebp too, and don't wait for it to fail.

That particular BIOS has been fixed, but there is a possibility that this is responsible for other occasional reports of early boot failure, and it does not hurt to add %esi to the clobbers. -stable candidate patch.
