* coda: remove CODA_STORE/CODA_RELEASE upcallsJan Harkes2007-07-21
| | | | | | | | | | | | | | | | | | | | | | | This is an variation on the patch sent by Christoph Hellwig which kills file_count abuse by the Coda kernel module by moving the coda_flush functionality into coda_release. However part of reason we were using the coda_flush callback was to allow Coda to pass errors that occur during writeback from the userspace cache manager back to close(). As Al Viro explained on linux-fsdevel, it is impossible to guarantee that such errors can in fact be returned back to the caller. There are many cases where the last reference to a file is not released by the close system call and it is also impossible to pick some close as a 'last-close' and delay it until all other references have been destroyed. The CODA_STORE/CODA_RELEASE upcall combination is clearly a broken design, and it is better to remove it completely.

* splice: fix bad unlock_page() in error caseJens Axboe2007-07-20
| | | | | | | | | | | | | If add_to_page_cache_lru() fails, the page will not be locked. But splice jumps to an error path that does a page release and unlock, causing a BUG() in unlock_page(). Fix this by adding one more label that just releases the page. This bug was actually triggered on EL5 by gurudas pai <gurudas.pai@oracle.com> using fio.

* AFS: Use patched rxrpc_kernel_send_data() correctlyDavid Howells2007-07-20
| | | | | | | | | | | | | Fix afs_send_simple_reply() to accept a greater-than-zero return value from rxrpc_kernel_send_data() as being a successful return rather than thinking it an error and aborting the call. rxrpc_kernel_send_data() previously returned zero incorrectly when it worked successfully, but has been patched to return the number of bytes it transmitted.

* mm: Remove slab destructors from kmem_cache_create().Paul Mundt2007-07-19
| | | | | | | | | | | | | | Slab destructors were no longer supported after Christoph's c59def9f222d44bb7e2f0a559f2906191a0862d7 change. They've been BUGs for both slab and slub, and slob never supported them either. This rips out support for the dtor pointer from kmem_cache_create() completely and fixes up every single callsite in the kernel (there were about 224, not including the slab allocator definitions themselves, or the documentation references).

| | | | | | | | | | | | a) switch by loff_t == __cmpdi2 use.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When changing the file size by a truncate() call, we log the change in the inode size. However, we do not flush any outstanding data that might not have been written to disk, thereby violating the data/inode size update order. This can leave files full of NULLs on crash. Hence if we are truncating the file, flush any unwritten data that may lie between the curret on disk inode size and the new inode size that is being logged to ensure that ordering is preserved.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many filesystems need a ->page-mkwrite callout to correctly set up pages that have been written to by mmap. This is especially important when mmap is writing into holes as it allows filesystems to correctly account for and allocate space before the mmap write is allowed to proceed. Protection against truncate races is provided by locking the page and checking to see whether the page mapping is correct and whether it is beyond EOF so we don't end up allowing allocations beyond the current EOF or changing EOF as a result of a mmap write.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The value of nperbucket calculated here is too small--we should be rounding up instead of down--with the result that the index j in the following loop can overflow the raparm_hash array. At least in my case, the next thing in memory turns out to be export_table, so the symptoms I see are crashes caused by the appearance of four zeroed-out export entries in the first bucket of the hash table of exports (which were actually entries in the readahead cache, a pointer to which had been written to the export table in this initialization code). It looks like the bug was probably introduced with commit fce1456a19f5c08b688c29f00ef90fdfa074c79b ("knfsd: make the readahead params cache SMP-friendly").

* | coda: coda doesn't track atimeJan Harkes2007-07-19
| | | | | | | | | | | | | | | | | | | | | | | | Set MS_NOATIME flag to avoid unnecessary calls when the coda inode is accessed. Also, set statfs.f_bsize to 4k. 1k is obviously too small for the suggested IO size.
