Instead of always splitting the file offset into 32-bit 'high' and 'low' parts, just split them into the largest natural word-size - which in C terms is 'unsigned long'. This allows 64-bit architectures to avoid the unnecessary 32-bit shifting and masking for native format (while the compat interfaces will obviously always have to do it). This also changes the order of 'high' and 'low' to be "low first". Why? Because when we have it like this, the 64-bit system calls now don't use the "pos_high" argument at all, and it makes more sense for the native system call to simply match the user-mode prototype. This results in a much more natural calling convention, and allows the compiler to generate much more straightforward code. On x86-64, we now generate testq %rcx, %rcx # pos_l js .L122 #, movq %rcx, -48(%rbp) # pos_l, pos from the C source loff_t pos = pos_from_hilo(pos_h, pos_l); ... if (pos < 0) return -EINVAL; and the 'pos_h' register isn't even touched. It used to generate code like mov %r8d, %r8d # pos_low, pos_low salq $32, %rcx #, tmp71 movq %r8, %rax # pos_low, pos.386 orq %rcx, %rax # tmp71, pos.386 js .L122 #, movq %rax, -48(%rbp) # pos.386, pos which isn't _that_ horrible, but it does show how the natural word size is just a more sensible interface (same arguments will hold in the user level glibc wrapper function, of course, so the kernel side is just half of the equation!) Note: in all cases the user code wrapper can again be the same. You can just do #define HALF_BITS (sizeof(unsigned long)*4) __syscall(PWRITEV, fd, iov, count, offset, (offset >> HALF_BITS) >> HALF_BITS); or something like that. That way the user mode wrapper will also be nicely passing in a zero (it won't actually have to do the shifts, the compiler will understand what is going on) for the last argument. And that is a good idea, even if nobody will necessarily ever care: if we ever do move to a 128-bit lloff_t, this particular system call might be left alone. Of course, that will be the least of our worries if we really ever need to care, so this may not be worth really caring about.

pci mmap code was doing memtype reserve for a while now. Recently we added memtype tracking in remap_pfn_range, and pci code indirectly calls remap_pfn_range. So, we don't need seperate tracking in pci code anymore. Which means a patch that removes ~50 lines of code :-). Also, recently we found out that the pci tracking is not working as we expect it to work in some cases. Specifically, userlevel X mmap of pci, with some recent version of X, is having a problem with vm_page_prot getting reset. The pci tracking uses vm_page_prot to pass on the protection type from parent to child during fork. a) Parent does a pci mmap b) We look at PAT and get either UC_MINUS or WC mapping for parent c) Store that mapping type in vma vm_page_prot for future use d) This thread does a fork e) Fork results in mmap_ops ->open for the child process f) We get the vm_page_prot from vma and reserve that type for the child process But, between c) and e) above, the vma vm_page_prot is getting reset to zero. This results in PAT reserve failing at the time of fork as in here. http://marc.info/?l=linux-kernel&m=123858163103240&w=2 This cleanup makes the above problem go away as we do not depend on vm_page_prot in our PAT code anymore.

During recovery, a node recovers orphans in it's slot and the dead node(s). But if the dead nodes were holding orphans in offline slots, they will be left unrecovered. If the dead node is the last one to die and is holding orphans in other slots and is the first one to mount, then it only recovers it's own slot, which leaves orphans in offline slots. This patch queues complete_recovery to clean orphans for all offline slots during mount and node recovery.

A page can have multiple buffers and even if a page is not uptodate, some buffers can be uptodate on pagesize != blocksize environment. This aops checks that all buffers which correspond to a part of a file that we want to read are uptodate. If so, we do not have to issue actual read IO to HDD even if a page is not uptodate because the portion we want to read are uptodate. "block_is_partially_uptodate" function is already used by ext2/3/4. With the following patch random read/write mixed workloads or random read after random write workloads can be optimized and we can get performance improvement.

For nfs exporting, ocfs2_get_dentry() returns the dentry for fh. ocfs2_get_dentry() may read from disk when the inode is not in memory, without any cross cluster lock. this leads to the file system loading a stale inode. This patch fixes above problem. Solution is that in case of inode is not in memory, we get the cluster lock(PR) of alloc inode where the inode in question is allocated from (this causes node on which deletion is done sync the alloc inode) before reading out the inode itsself. then we check the bitmap in the group (the inode in question allcated from) to see if the bit is clear. if it's clear then it's stale. if the bit is set, we then check generation as the existing code does. We have to read out the inode in question from disk first to know its alloc slot and allot bit. And if its not stale we read it out using ocfs2_iget(). The second read should then be from cache. And also we have to add a per superblock nfs_sync_lock to cover the lock for alloc inode and that for inode in question. this is because ocfs2_get_dentry() and ocfs2_delete_inode() lock on them in reverse order. nfs_sync_lock is locked in EX mode in ocfs2_get_dentry() and in PR mode in ocfs2_delete_inode(). so that mutliple ocfs2_delete_inode() can run concurrently in normal case.

The lifetime of a mle is limited to the duration of the lockres mastery process. While typically this lifetime is fairly short, we have noticed the number of mles explode under certain circumstances.
