* [BLOCK] Don't pin lots of memory in mempoolsJens Axboe2007-04-30
| | | | | | | | | | | | | | Currently we scale the mempool sizes depending on memory installed in the machine, except for the bio pool itself which sits at a fixed 256 entry pre-allocation. There's really no point in "optimizing" this OOM path, we just need enough preallocated to make progress. A single unit is enough, lets scale it down to 2 just to be on the safe side. This patch saves ~150kb of pinned kernel memory on a 32-bit box. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

| * sis900: Allocate rx replacement buffer before rx operationNeil Horman2007-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Just found a hole in my last patch. It was reported to me that shortly after we integrated this patch. The report was of an oops that took place inside of netif_rx when using the sis900 driver. Looking at my origional patch I noted that there was a spot between the new skb_alloc and the refill_rx_ring label where skb got reassigned to the pointer currently held in the rx_ring for the purposes of receiveing the frame. The result of this is however that the buffer that gets passed to netif_rx (if it is called), then gets placed right back into the rx_ring. So if you receive frames fast enough the skb being processed by the network stack can get corrupted. The reporter is testing out the fix I've written for this below (I'm not near my hardware at the moment to test myself), but I wanted to post it for review ASAP. I'll post test results when I hear them, but I think this is a pretty straightforward fix. It just uses a separate pointer to do the rx operation, so that we don't improperly reassign the pointer that we use to refill the rx ring.

| * | | [JFFS2] Improve read_inode memory usage, v2.David Woodhouse2007-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We originally used to read every node and allocate a jffs2_tmp_dnode_info structure for each, before processing them in (reverse) version order and discarding the ones which are obsoleted by later nodes. With huge logfiles, this behaviour caused memory problems. For example, a file involved in OLPC trac #1292 has 1822391 nodes, and would cause the XO machine to run out of memory during the first stage of read_inode(). Instead of just inserting nodes into a tree in version order as we find them, we now put them into a tree in order of their offset within the file, which allows us to immediately discard nodes which are completely obsoleted. We don't use a full tree with 'fragments' pointing to the real data structure, as we do in the normal fragtree. We sort only on the start address, and add an 'overlapped' flag to the tmp_dnode_info to indicate that the node in question is (partially) overlapped by another. When the scan is complete, we start at the end of the file, adding each node to a real fragtree as before. Where the node is non-overlapped, we just add it (it doesn't matter that it's not the latest version; there is no overlap). When the node at the end of the tree _is_ overlapped, we sort it and all its overlapping nodes into version order and then add them to the fragtree in that order. This 'early discard' reduces the peak allocation of tmp_dnode_info structures from 1.8M to a mere 62872 (3.5%) in the degenerate case referenced above. This version of the patch also correctly rememembers the highest node version# seen for an inode when it's scanned. Signed-off-by: David Woodhouse <dwmw2@infradead.org>

I/O unit (e.g. NAND page) to be read more then once. Namely, at the beginning we do not know which node type we read, so we read so we assume we read the directory entry, because it has the smallest node header. When we read it, we read up to the next min. I/O unit, just because if later we'll need to read more, we already have this data. If it turns out to be that the node is not directory entry, and we need more data, and we did not read it because it sits in the next min. I/O unit, we read the whole next (or several next) min. I/O unit(s). And if it happens to be that we read a data node, and we've read part of its data, we calculate partial CRC. So if later we need to check data CRC, we'll only read the rest of the data from further min. I/O units and continue CRC checking. This code was a bit messy and buggy. The bug was that it assumed relatively large min. I/O unit, so that the largest node header could overlap only one min. I/O unit boundary. This parch clean-ups the code a bit and fixes this bug. The patch was not tested on flash with small min. I/O unit, like NOR-ECC, nut it was tested on NAND with 512 bytes NAND page, so it at least does not break NAND. It was also tested with mtdram so it should not break NOR. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org>

| * | | [MTD] [NAND] Casting bug in nand_default_block_markbadAndre Renaud2007-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a slight bug in nand_default_block_markbad, where the offset is cast to an integer, prior to being shifted. This means that on large offsets, it is incorrectly doing a signed shift & losing bits. Fixed this by doing the cast after the shift (as is done elsewhere in the code).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for AT26Fxxx dataflash devices. These devices have a quite different commandset than the AT45xxx chips, which are handled by at91_dataflash.c, so a combined driver turned out to be more ugly than useful. Tested only on AT26F004.
