2009-02-02T17:53:18Z

commit 3ddf1e7f57237ac7c5d5bfb7058f1ea4f970b661 upstream. Fix the leaking file reference if allocation or initialization of fuse_conn failed. Signed-off-by: Miklos Szeredi Signed-off-by: Greg Kroah-Hartman

fuse: destroy bdi on umount

2009-02-02T17:53:18Z

commit 26c3679101dbccc054dcf370143941844ba70531 upstream. If a fuse filesystem is unmounted but the device file descriptor remains open and a new mount reuses the old device number, then the mount fails with EEXIST and the following warning is printed in the kernel log: WARNING: at fs/sysfs/dir.c:462 sysfs_add_one+0x35/0x3d() sysfs: duplicate filename '0:15' can not be created The cause is that the bdi belonging to the fuse filesystem was destoryed only after the device file was released. Fix this by calling bdi_destroy() from fuse_put_super() instead. Signed-off-by: Miklos Szeredi Signed-off-by: Greg Kroah-Hartman

fuse: add missing fuse_request_free

2008-10-16T14:08:56Z

The error handling code for the second call to fuse_request_alloc should include freeing the result of the first one. This bug was found by the Coccinelle project: http://www.emn.fr/x-info/coccinelle/ Signed-off-by: Julia Lawall Signed-off-by: Miklos Szeredi

vfs: Use const for kernel parser table

2008-10-13T17:10:37Z

This is a much better version of a previous patch to make the parser tables constant. Rather than changing the typedef, we put the "const" in all the various places where its required, allowing the __initconst exception for nfsroot which was the cause of the previous trouble. This was posted for review some time ago and I believe its been in -mm since then. Signed-off-by: Steven Whitehouse Cc: Alexander Viro Signed-off-by: Linus Torvalds

SL*B: drop kmem cache argument from constructor

2008-07-26T19:00:07Z

Kmem cache passed to constructor is only needed for constructors that are themselves multiplexeres. Nobody uses this "feature", nor does anybody uses passed kmem cache in non-trivial way, so pass only pointer to object. Non-trivial places are: arch/powerpc/mm/init_64.c arch/powerpc/mm/hugetlbpage.c This is flag day, yes.

fuse: nfs export special lookups

2008-07-25T17:53:48Z

Implement the get_parent export operation by sending a LOOKUP request with ".." as the name. Implement looking up an inode by node ID after it has been evicted from the cache. This is done by seding a LOOKUP request with "." as the name (for all file types, not just directories). The filesystem can set the FUSE_EXPORT_SUPPORT flag in the INIT reply, to indicate that it supports these special lookups. Thanks to John Muir for the original implementation of this feature.

fuse: add export operations

2008-07-25T17:53:48Z

Implement export_operations, to allow fuse filesystems to be exported to NFS. This feature has been in the out-of-tree fuse module, and is widely used and tested. It has not been originally merged into mainline, because doing the NFS export in userspace was thought to be a cleaner and more efficient way of doing it, than through the kernel. While that is true, it would also have involved a lot of duplicated effort at reimplementing NFS exporting (all the different versions of the protocol). This effort was unfortunately not undertaken by anyone, so we are left with doing it the easy but less efficient way. If this feature goes in, the out-of-tree fuse module can go away, which would have several advantages: - not having to maintain two versions - less confusion for users - no bugs due to kernel API changes Comment from hch: - Use the same fh_type values as XFS, since we use the same fh encoding.

fuse: fix thinko in max I/O size calucation

2008-06-18T01:08:10Z

Use max not min to enforce a lower limit on the max I/O size. This bug was introduced by "fuse: fix max i/o size calculation" (commit e5d9a0df07484d6d191756878c974e4307fb24ce).

fuse: fix bdi naming conflict

2008-05-24T16:56:07Z

Fuse allocates a separate bdi for each filesystem, and registers them in sysfs with "MAJOR:MINOR" of sb->s_dev (st_dev). This works fine for anon devices normally used by fuse, but can conflict with an already registered BDI for "fuseblk" filesystems, where sb->s_dev represents a real block device. In particularl this happens if a non-partitioned device is being mounted. Fix by registering with a different name for "fuseblk" filesystems. Thanks to Ioan Ionita for the bug report.
