2007-11-069p: use copy of the options value instead of originalLatchesar Ionkov
v9fs_parse_options function uses strsep which modifies the value of the v9ses->options field. That modified value is later passed to the function that creates the transport potentially making the transport creation function to fail. This patch creates a copy of v9ses->option field that v9fs_parse_options function uses instead of the original value.

The regression was caused by: commit[a32ea1e1f925399e0d81ca3f7394a44a6dafa12c] Fix read/truncate race This causes ntfs_readpage() to be called for a zero i_size inode, which failed when the file was compressed and non-resident.

2007-10-30locks: fix possible infinite loop in posix deadlock detectionJ. Bruce Fields
It's currently possible to send posix_locks_deadlock() into an infinite loop (under the BKL). For now, fix this just by bailing out after a few iterations. We may want to fix this in a way that better clarifies the semantics of deadlock detection. But that will take more time, and this minimal fix is probably adequate for any realistic scenario, and is simple enough to be appropriate for applying to stable kernels now.

2007-10-30revert "ufs: Fix mount check in ufs_fill_super()"Andrew Morton
Evgeniy said: I wonder on what type of UFS do you test this patch? NetBSD and FreeBSD do not use "fs_state", they use "fs_clean" flag, only Solaris does check like this: fs_state + fs_time == FSOK. That's why parentheses was like that. At now with linux-2.6.24-rc1-git1, I get: fs need fsck, but NetBSD's fsck says that's all ok. I suggest revert this patch.

2007-10-26[NET]: Marking struct pernet_operations __net_initdata was inappropriateEric W. Biederman
It is not safe to to place struct pernet_operations in a special section. We need struct pernet_operations to last until we call unregister_pernet_subsys. Which doesn't happen until module unload. So marking struct pernet_operations is a disaster for modules in two ways. - We discard it before we call the exit method it points to. - Because I keep struct pernet_operations on a linked list discarding it for compiled in code removes elements in the middle of a linked list and does horrible things for linked insert. So this looks safe assuming __exit_refok is not discarded for modules. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2007-10-23NFS: Fix for bug in handling of errors for O_DIRECT writesNeil Brown
Commit eda3cef8dd2b83875affe82595db9d0c278879b2 ("NFS: Fix error handling in nfs_direct_write_result()") ensured that if a WRITE returns an error, then data->res.verf->committed is not tested (as it is not initialised). Then commit 60fa3f769f7651a60125a0f44e3ffe3246d7cf39 ("NFS: Fix two bugs in the O_DIRECT write code") inadvertently reverted this while fixing other problems. So move the test so that we never examine ->committed in an error case, and fix a speeling error while we are there.

2007-10-22exportfs: add new methodsChristoph Hellwig
Add the guts for the new filesystem API to exportfs. There's now a fh_to_dentry method that returns a dentry for the object looked for given a filehandle fragment, and a fh_to_parent operation that returns the dentry for the encoded parent directory in case the file handle contains it. There are default implementations for these methods that only take a callback for an nfs-enhanced iget variant and implement the rest of the semantics.

2007-10-22exportfs: add fid typeChristoph Hellwig
This patchset is a medium scale rewrite of the export operations interface. The goal is to make the interface less complex, and easier to understand from the filesystem side, aswell as preparing generic support for exporting of 64bit inode numbers. This touches all nfs exporting filesystems, and I've done testing on all of the filesystems I have here locally (xfs, ext2, ext3, reiserfs, jfs) This patch: Add a structured fid type so that we don't have to pass an array of u32 values around everywhere. It's a union of possible layouts. As a start there's only the u32 array and the traditional 32bit inode format, but there will be more in one of my next patchset when I start to document the various filehandle formats we have in lowlevel filesystems better. Also add an enum that gives the various filehandle types human- readable names. Note: Some people might think the struct containing an anonymous union is ugly, but I didn't want to pass around a raw union type.

2007-10-22ext2: avoid rec_len overflow with 64KB block sizeJan Kara
