* [JFFS2] Debug code simplification, update TODOArtem B. Bityutskiy2005-11-06
| | | | | | | | Simplify the debugging code further. Update the TODO list Signed-off-by: Artem B. Bityutskiy <dedekind@infradead.org> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
* [JFFS2] Account summary space in reserved_size.Ferenc Havasi2005-11-06
| | | | | | | | | | | Always keep valid data in reserved_size. It did not cause problems, but the reservation code was unoptimal when centralized summary was active or the size of the erase block was very small.

* [JFFS2] Call summary collector for all mtd devices with writev supportFerenc Havasi2005-11-06
| | | | | | | | | Do the summary collection in the right place. If the device was not writebuffered but had c->mtd->writev function (e.g. blkmtd) the summary collector function was not called. Signed-off-by: Ferenc Havasi <havasi@inf.u-szeged.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

* [JFFS2] Add erase block summary support (mount time improvement)Ferenc Havasi2005-11-06
| | | | | | | | | | | | | | | | | | The goal of summary is to speed up the mount time. Erase block summary (EBS) stores summary information at the end of every (closed) erase block. It is no longer necessary to scan all nodes separetly (and read all pages of them) just read this "small" summary, where every information is stored which is needed at mount time. This summary information is stored in a JFFS2_FEATURE_RWCOMPAT_DELETE. During the mount process if there is no summary info the orignal scan process will be executed. EBS works with NAND and NOR flashes, too. There is a user space tool called sumtool to generate this summary information for a JFFS2 image.

* [JFFS2] Fix slab panicArtem B. Bityutskiy2005-11-06
| | | | | | | | | | When JFFS22 is unable to read the root inode, the bad root inode object is not freed and remains sticked in the jffs2_i slab cache. When we further try to free the slab cache (e.g., on rmmod jffs2), slab allocator subsystem panics. Fix this bug. Signed-off-by: Artem B.

* [JFFS2] Use f->target instead of f->dents for symlink targetArtem B. Bityutskiy2005-11-06
| | | | | | | | | | JFFS2 uses f->dents to store the pointer to the symlink target string (in case the inode is symlink). This is somewhat ugly to use the same field for different reasons. Introduce distinct field f->target for this purpose. Note, f->fragtree, f->dents, f->target may probably be put in a union. Signed-off-by: Artem B.

* NFSv4: Teach NFSv4 to cache locks when we hold a delegationTrond Myklebust2005-11-04
| | | | | | | Now that we have a method of dealing with delegation recalls, actually enable the caching of posix and BSD locks. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Recover locks too when returning a delegationTrond Myklebust2005-11-04
| | | | | | | | | | Delegations allow us to cache posix and BSD locks, however when the delegation is recalled, we need to "flush the cache" and send the cached LOCK requests to the server. This patch sets up the mechanism for doing so. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

| | | | | | | | I missed this one... Any form of rename will result in a delegation recall, so it is more efficient to return the one we hold before trying the rename. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* NFSv4: Fix problem with OPEN_DOWNGRADETrond Myklebust2005-11-04
| | | | | | | | | | | | | | | | | RFC 3530 states that for OPEN_DOWNGRADE "The share_access and share_deny bits specified must be exactly equal to the union of the share_access and share_deny bits specified for some subset of the OPENs in effect for current openowner on the current file. Setattr is currently violating the NFSv4 rules for OPEN_DOWNGRADE in that it may cause a downgrade from OPEN4_SHARE_ACCESS_BOTH to OPEN4_SHARE_ACCESS_WRITE despite the fact that there exists no open file with O_WRONLY access mode. Fix the problem by replacing nfs4_find_state() with a modified version of nfs_find_open_context(). Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

| * [XFS] fix XFS quota for modular XFS buildsNathan Scott2005-11-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Cannot build XFS filesystem support as module with quota support. It works only when the XFS filesystem support is compiled into the kernel. Menuconfig prevents from setting CONFIG_XFS_FS=m and CONFIG_XFS_QUOTA=y. How to reproduce: configure the XFS filesystem with quota support as module. The resulting kernel won't have quota support compiled into xfs.ko. Fix: Changing the fs/xfs/Kconfig file from tristate to bool lets you configure the quota support to be compiled into the XFS module. The Makefile-linux-2.6 checks only for CONFIG_XFS_QUOTA=y.
