* [PATCH] inode-diet: Eliminate i_blksize from the inode structureTheodore Ts'o2006-09-27
| | | | | | | | | | | | | | | | This eliminates the i_blksize field from struct inode. Filesystems that want to provide a per-inode st_blksize can do so by providing their own getattr routine instead of using the generic_fillattr() function. Note that some filesystems were providing pretty much random (and incorrect) values for i_blksize.

* [PATCH] 9p: fix fid behavior on failed removeEric Van Hensbergen2006-07-31
| | | | | | | | | | | | | | | | | Based on a bug report from Russ Ross <russruss@gmail.com> According to the spec: "The remove request asks the file server both to remove the file represented by fid and to clunk the fid, even if the remove fails." but the Linux client seems to expect the fid to be valid after a failed remove attempt. Specifically, I'm getting this behavior when attempting to remove a non-empty directory.

* | [PATCH] VFS: Permit filesystem to override root dentry on mountDavid Howells2006-06-23
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Extend the get_sb() filesystem operation to take an extra argument that permits the VFS to pass in the target vfsmount that defines the mountpoint. The filesystem is then required to manually set the superblock and root dentry pointers. For most filesystems, this should be done with simple_set_mnt() which will set the superblock pointer and then set the root dentry to the superblock's s_root (as per the old default behaviour). The get_sb() op now returns an integer as there's now no need to return the superblock pointer. This patch permits a superblock to be implicitly shared amongst several mount points, such as can be done with NFS to avoid potential inode aliasing. In such a case, simple_set_mnt() would not be called, and instead the mnt_root and mnt_sb would be set directly. The patch also makes the following changes: (*) the get_sb_*() convenience functions in the core kernel now take a vfsmount pointer argument and return an integer, so most filesystems have to change very little. (*) If one of the convenience function is not used, then get_sb() should normally call simple_set_mnt() to instantiate the vfsmount. This will always return 0, and so can be tail-called from get_sb(). (*) generic_shutdown_super() now calls shrink_dcache_sb() to clean up the dcache upon superblock destruction rather than shrink_dcache_anon(). This is required because the superblock may now have multiple trees that aren't actually bound to s_root, but that still need to be cleaned up. The currently called functions assume that the whole tree is rooted at s_root, and that anonymous dentries are not the roots of trees which results in dentries being left unculled. However, with the way NFS superblock sharing are currently set to be implemented, these assumptions are violated: the root of the filesystem is simply a dummy dentry and inode (the real inode for '/' may well be inaccessible), and all the vfsmounts are rooted on anonymous[*] dentries with child trees. [*] Anonymous until discovered from another tree. (*) The documentation has been adjusted, including the additional bit of changing ext2_* into foo_* in the documentation.

* [PATCH] v9fs: signal handling fixesLatchesar Ionkov2006-05-15
| | | | | | | | | | | | | | | Multiple races can happen when v9fs is interrupted by a signal and Tflush message is sent to the server. After v9fs sends Tflush it doesn't wait until it receives Rflush, and possibly the response of the original message. This behavior may confuse v9fs what fids are allocated by the file server.

* [PATCH] 9p: fix name consistency problemsEric Van Hensbergen2006-03-25
| | | | | | | | | | | | | | | | There were a number of conflicting naming schemes used in the v9fs project. The directory was fs/9p, but MAINTAINERS and Documentation referred to v9fs. The module name itself was 9p2000, and the file system type was 9P. This patch attempts to clean that up, changing all references to 9p in order to match the directory name. We'll also start using 9p instead of v9fs as our patch prefix. There is also a minor consistency cleanup in the options changing the name option to uname in order to more closely match the Plan 9 options.

| | | | | | | | | | | | | | | | If a file is not found in v9fs_vfs_lookup, the function creates negative dentry, but doesn't assign any dentry ops.

* [PATCH] v9fs: simplify fid mappingEric Van Hensbergen2006-03-02
| | | | | | | | | | | | | | | | | | | | v9fs has been plagued by an over-complicated approach trying to map Linux dentry semantics to Plan 9 fid semantics. Our previous approach called for aggressive flushing of the dcache resulting in several problems (including wierd cwd behavior when running /bin/pwd). This patch dramatically simplifies our handling of this fid management. Fids will not be clunked as promptly, but the new approach is more functionally correct. We now clunk un-open fids only when their dentry ref_count reaches 0 (and d_delete is called). Another simplification is we no longer seek to match fids to the process-id or uid of the action initiator. The uid-matching will need to be revisited when we fix the security model.

* [PATCH] v9fs: fix corner cases when flushing requestLatchesar Ionkov2006-02-03
| | | | | | | | | | | | | | | | | | | | When v9fs_mux_rpc sends a 9P message, it may be put in the queue of unsent request. If the user process receives a signal, v9fs_mux_rpc sets the request error to ERREQFLUSH and assigns NULL to request's send message. If the message was still in the unsent queue, v9fs_write_work would produce an oops while processing it. The patch makes sure that requests that are being flushed are moved to the pending requests queue safely. If a request is being flushed, don't remove it from the list of pending requests even if it receives a reply before the flush is acknoledged. The request will be removed during from the Rflush handler (v9fs_mux_flush_cb).

* [PATCH] v9fs: fix fid management in v9fs_createLatchesar Ionkov2006-01-08
| | | | | | | | | | | | | | v9fs_create doesn't manage correctly the fids when it is called to create a directory.. The fid created by the create 9P call (newfid) and the one created by walking to already created file (wfidno) are not used consistently. This patch cleans up the usage of newfid and wfidno.

* [PATCH] v9fs: fix fd_closeEric Van Hensbergen2006-01-08
| | | | | | | | | | | | | If a 9pfs server crashes, v9fs_fd_close() is called. Subsequently, in cleaning up by performing a umount() on the FS that was provided by this server v9fs_fd_close() is called again, and uses the old, freed valus of trans->priv. This patch ensures that trans->priv can be freed only once, otherwise this function bails early.

* [PATCH] Fix and add EXPORT_SYMBOL(filemap_write_and_wait)OGAWA Hirofumi2006-01-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch add EXPORT_SYMBOL(filemap_write_and_wait) and use it. See mm/filemap.c: And changes the filemap_write_and_wait() and filemap_write_and_wait_range(). Current filemap_write_and_wait() doesn't wait if filemap_fdatawrite() returns error. However, even if filemap_fdatawrite() returned an error, it may have submitted the partially data pages to the device. (e.g. in the case of -ENOSPC) <quotation> Andrew Morton writes, If filemap_fdatawrite() returns an error, this might be due to some I/O problem: dead disk, unplugged cable, etc. Given the generally crappy quality of the kernel's handling of such exceptions, there's a good chance that the filemap_fdatawait() will get stuck in D state forever. </quotation> So, this patch doesn't wait if filemap_fdatawrite() returns the -EIO. Trond, could you please review the nfs part? Especially I'm not sure, nfs must use the "filemap_fdatawrite(inode->i_mapping) == 0", or not.
