2007-09-02[JFFS2] fix write deadlock regressionJason Lunz
I've bisected the deadlock when many small appends are done on jffs2 down to this commit: commit 6fe6900e1e5b6fa9e5c59aa5061f244fe3f467e2 Author: Nick Piggin <npiggin@suse.de> Date: Sun May 6 14:49:04 2007 -0700 mm: make read_cache_page synchronous Ensure pages are uptodate after returning from read_cache_page, which allows us to cut out most of the filesystem-internal PageUptodate calls. I didn't have a great look down the call chains, but this appears to fixes 7 possible use-before uptodate in hfs, 2 in hfsplus, 1 in jfs, a few in ecryptfs, 1 in jffs2, and a possible cleared data overwritten with readpage in block2mtd. All depending on whether the filler is async and/or can return with a !uptodate page. It introduced a wait to read_cache_page, as well as a read_cache_page_async function equivalent to the old read_cache_page without any callers. Switching jffs2_gc_fetch_page to read_cache_page_async for the old behavior makes the deadlocks go away, but maybe reintroduces the use-before-uptodate problem? I don't understand the mm/fs interaction well enough to say. [It's fine. dwmw2.] Signed-off-by: Jason Lunz <lunz@falooley.org> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
2007-09-01NFS: Fix a write request leak in nfs_invalidate_page()Trond Myklebust
Ryusuke Konishi says: The recent truncate_complete_page() clears the dirty flag from a page before calling a_ops->invalidatepage(), ^^^^^^ static void truncate_complete_page(struct address_space *mapping, struct page *page) { ... cancel_dirty_page(page, PAGE_CACHE_SIZE); <--- Inserted here at kernel 2.6.20 if (PagePrivate(page)) do_invalidatepage(page, 0); ---> will call a_ops->invalidatepage() ... } and this is disturbing nfs_wb_page_priority() from calling nfs_writepage_locked() that is expected to handle the pending request (=nfs_page) associated with the page. int nfs_wb_page_priority(struct inode *inode, struct page *page, int how) { ... if (clear_page_dirty_for_io(page)) { ret = nfs_writepage_locked(page, &wbc); if (ret < 0) goto out; } ... } Since truncate_complete_page() will get rid of the page after a_ops->invalidatepage() returns, the request (=nfs_page) associated with the page becomes a garbage in nfs_inode->nfs_page_tree. ------------------------ Fix this by ensuring that nfs_wb_page_priority() recognises that it may also need to clear out non-dirty pages that have an nfs_page associated with them.

2007-08-31NFS: Fix the mount regressionTrond Myklebust
This avoids the recent NFS mount regression (returning EBUSY when mounting the same filesystem twice with different parameters). The best I can do given the constraints appears to be to have the kernel first look for a superblock that matches both the fsid and the user-specified mount options, and then spawn off a new superblock if that search fails. Note that this is not the same as specifying nosharecache everywhere since nosharecache will never attempt to match an existing superblock.

2007-08-31Do not use the ia64 clocksource on non-ia64 architecturesLinus Torvalds
The HPET clocksource in drivers/char/hpet.c was written as generic code for ia64, but it is not yet ready to replace the native HPET clocksource implementations that the i386/x86-64 architectures use. On x86[-64], trying to register this clocksource results in potentially multiple hpet-based clocksources being registered, and if the ia64 one is chosen on x86_64 some users have experienced hangs. Eventually all three architectures may end up using the same code, but that is not the case right now.
