* [PATCH] jbd: add lock annotation to jbd_sync_bhJosh Triplett2006-09-271-0/+1
| | | | | | | | | | | jbd_sync_bh releases journal->j_list_lock. Add a lock annotation to this function so that sparse can check callers for lock pairing, and so that sparse will not complain about this function since it intentionally uses the lock in this manner.

* | [PATCH] mm: tracking shared dirty pagesPeter Zijlstra2006-09-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tracking of dirty pages in shared writeable mmap()s. The idea is simple: write protect clean shared writeable pages, catch the write-fault, make writeable and set dirty. On page write-back clean all the PTE dirty bits and write protect them once again. The implementation is a tad harder, mainly because the default backing_dev_info capabilities were too loosely maintained. Hence it is not enough to test the backing_dev_info for cap_account_dirty. The current heuristic is as follows, a VMA is eligible when: - its shared writeable (vm_flags & (VM_WRITE|VM_SHARED)) == (VM_WRITE|VM_SHARED) - it is not a 'special' mapping (vm_flags & (VM_PFNMAP|VM_INSERTPAGE)) == 0 - the backing_dev_info is cap_account_dirty mapping_cap_account_dirty(vma->vm_file->f_mapping) - f_op->mmap() didn't change the default page protection Page from remap_pfn_range() are explicitly excluded because their COW semantics are already horrid enough (see vm_normal_page() in do_wp_page()) and because they don't have a backing store anyway. mprotect() is taught about the new behaviour as well. However it overrides the last condition. Cleaning the pages on write-back is done with page_mkclean() a new rmap call. It can be called on any page, but is currently only implemented for mapped pages, if the page is found the be of a VMA that accounts dirty pages it will also wrprotect the PTE. Finally, in fs/buffers.c:try_to_free_buffers(); remove clear_page_dirty() from under ->private_lock. This seems to be safe, since ->private_lock is used to serialize access to the buffers, not the page itself. This is needed because clear_page_dirty() will call into page_mkclean() and would thereby violate locking order.

* | [PATCH] jbd: fix commit of ordered data buffersJan Kara2006-09-261-69/+113
|/ | | | | | | | | | | | | | | | | | | | | | | | | Original commit code assumes, that when a buffer on BJ_SyncData list is locked, it is being written to disk. But this is not true and hence it can lead to a potential data loss on crash. Also the code didn't count with the fact that journal_dirty_data() can steal buffers from committing transaction and hence could write buffers that no longer belong to the committing transaction. Finally it could possibly happen that we tried writing out one buffer several times. The patch below tries to solve these problems by a complete rewrite of the data commit code. We go through buffers on t_sync_datalist, lock buffers needing write out and store them in an array. Buffers are also immediately refiled to BJ_Locked list or unfiled (if the write out is completed). When the array is full or we have to block on buffer lock, we submit all accumulated buffers for IO.

* [PATCH] autofs4: zero timeout prevents shutdownIan Kent2006-09-251-3/+3
| | | | | | | | | | | | | | If the timeout of an autofs mount is set to zero then umounts are disabled. This works fine, however the kernel module checks the expire timeout and goes no further if it is zero. This is not the right thing to do at shutdown as the module is passed an option to expire mounts regardless of their timeout setting. This patch allows autofs to honor the force expire option.

* ocfs2: Remove i_generation from inode lock namesMark Fasheh2006-09-2410-53/+170
| | | | | | | | | | | | | | | | | | | | | | | OCFS2 puts inode meta data in the "lock value block" provided by the DLM. Typically, i_generation is encoded in the lock name so that a deleted inode on and a new one in the same block don't share the same lvb. Unfortunately, that scheme means that the read in ocfs2_read_locked_inode() is potentially thrown away as soon as the meta data lock is taken - we cannot encode the lock name without first knowing i_generation, which requires a disk read. This patch encodes i_generation in the inode meta data lvb, and removes the value from the inode meta data lock name. This way, the read can be covered by a lock, and at the same time we can distinguish between an up to date and a stale LVB. This will help cold-cache stat(2) performance in particular. Since this patch changes the protocol version, we take the opportunity to do a minor re-organization of two of the LVB fields. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
