A couple of filesystems had trivial enough ->put_super (only kfree and NULLing of s_fs_info + stuff in there) to not get any locking: coda, cramfs, efs, hugetlbfs, omfs, qnx4, shmem, all others got the full treatment. Most of them probably don't need it, but I'd rather sort that out individually. Preferably after all the other BKL pushdowns in that area.

* | remove ->write_super call in generic_shutdown_superChristoph Hellwig2009-06-121-0/+3
|/ | | | | | | | | | | | | | | | | | | | | We just did a full fs writeout using sync_filesystem before, and if that's not enough for the filesystem it can perform it's own writeout in ->put_super, which many filesystems already do. Move a call to foofs_write_super into every foofs_put_super for now to guarantee identical behaviour until it's cleaned up by the individual filesystem maintainers. Exceptions: - affs already has identical copy & pasted code at the beginning of affs_put_super so no need to do it twice. - xfs does the right thing without it and I have changes pending for the xfs tree touching this are so I don't really need conflicts here..

| | | | | | | | | | | | | Erase errors such as: "Newly-erased block contained word 0xa4ef223e at offset 0x0296a014" and failure to write the clean marker, moves the offending erase block to erasing list before calling jffs2_erase_failed().

* [JFFS2] fix mount crash caused by removed nodesThomas Gleixner2009-02-211-9/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At scan time we observed following scenario: node A inserted node B inserted node C inserted -> sets overlapped flag on node B node A is removed due to CRC failure -> overlapped flag on node B remains while (tn->overlapped) tn = tn_prev(tn); ==> crash, when tn_prev(B) is referenced. When the ultimate node is removed at scan time and the overlapped flag is set on the penultimate node, then nothing updates the overlapped flag of that node. The overlapped iterators blindly expect that the ultimate node does not have the overlapped flag set, which causes the scan code to crash. It would be a huge overhead to go through the node chain on node removal and fix up the overlapped flags, so detecting such a case on the fly in the overlapped iterators is a simpler and reliable solution.

* [JFFS2] force the jffs2 GC daemon to behave a bit betterAndres Salomon2009-02-141-7/+11
| | | | | | | | | | | | | | | | | | | I've noticed some pretty poor behavior on OLPC machines after bootup, when gdm/X are starting. The GCD monopolizes the scheduler (which in turns means it gets to do more nand i/o), which results in processes taking much much longer than they should to start. As an example, on an OLPC machine going from OFW to a usable X (via auto-login gdm) takes 2m 30s. The majority of this time is consumed by the switch into graphical mode. With this patch, we cut a full 60s off of bootup time. After bootup, things are much snappier as well. Note that we have seen a CRC node error with this patch that causes the machine to fail to boot, but we've also seen that problem without this patch.

| * fs: symlink write_begin allocation context fixNick Piggin2009-01-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the write_begin/write_end aops, page_symlink was broken because it could no longer pass a GFP_NOFS type mask into the point where the allocations happened. They are done in write_begin, which would always assume that the filesystem can be entered from reclaim. This bug could cause filesystem deadlocks. The funny thing with having a gfp_t mask there is that it doesn't really allow the caller to arbitrarily tinker with the context in which it can be called. It couldn't ever be GFP_ATOMIC, for example, because it needs to take the page lock. The only thing any callers care about is __GFP_FS anyway, so turn that into a single flag. Add a new flag for write_begin, AOP_FLAG_NOFS. Filesystems can now act on this flag in their write_begin function. Change __grab_cache_page to accept a nofs argument as well, to honour that flag (while we're there, change the name to grab_cache_page_write_begin which is more instructive and does away with random leading underscores). This is really a more flexible way to go in the end anyway -- if a filesystem happens to want any extra allocations aside from the pagecache ones in ints write_begin function, it may now use GFP_KERNEL (rather than GFP_NOFS) for common case allocations (eg. ocfs2_alloc_write_ctxt, for a random example).

* | [MTD] update internal API to support 64-bit device sizeAdrian Hunter2008-12-101-2/+3
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | MTD internal API presently uses 32-bit values to represent device size. This patch updates them to 64-bits but leaves the external API unchanged. Extending the external API is a separate issue for several reasons. First, no one needs it at the moment. Secondly, whether the implementation is done with IOCTLs, sysfs or both is still debated. Thirdly external API changes require the internal API to be accepted first. Note that although the MTD API will be able to support 64-bit device sizes, existing drivers do not and are not required to do so, although NAND base has been updated. In general, changing from 32-bit to 64-bit values cause little or no changes to the majority of the code with the following exceptions: - printk message formats - division and modulus of 64-bit values - NAND base support - 32-bit local variables used by mtdpart and mtdconcat - naughtily assuming one structure maps to another in MEMERASE ioctl Signed-off-by: Adrian Hunter <ext-adrian.hunter@nokia.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

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.

| | | | | | | | | | | | | | | | | | | | | | | | Adding the ability to get a physical address from point() in addition to virtual address. This physical address is required for XIP of userspace code from flash.

| * [JFFS2] Track parent inode for directories (for NFS export)David Woodhouse2008-05-0112-42/+70
| | | | | | | | | | | | | | | | To support NFS export, we need to know the parent inode of directories. Rather than growing the jffs2_inode_cache structure, share space with the nlink field -- which was always set to 1 for directories anyway. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
| * [JFFS2] Invert last argument of jffs2_gc_fetch_inode(), make it boolean.David Woodhouse2008-05-014-7/+8
| | | | | | | | | | | | | | We don't actually care about nlink; we only care whether the inode in question is unlinked or not. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
| * [JFFS2] Quiet lockdep false positive.David Woodhouse2008-05-012-3/+10
| | | | | | | | | | | | | | | | | | Don't hold f->sem while calling into jffs2_do_create(). It makes lockdep unhappy, and we don't really need it -- the _reason_ it's a false positive is because nobody else can see this inode yet and so nobody will be trying to lock it anyway.

| | | | | | | | | | | | | | | | Ditch a couple of pointless casts from void *, and use the normal variable name 'f' for jffs2_inode_info pointers -- especially since it actually shows up in lockdep reports. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
