mtd: blktrans: Hotplug fixes

2010-02-26T17:05:26Z

* Add locking where it was missing. * Don't do a get_mtd_device in blktrans_open because it would lead to a deadlock; instead do that in add_mtd_blktrans_dev. * Only free the mtd_blktrans_dev structure when the last user exits. * Flush request queue on device removal. * Track users, and call tr->release in del_mtd_blktrans_dev Due to that ->open and release aren't called more that once. Now it is safe to call del_mtd_blktrans_dev while the device is still in use. Signed-off-by: Maxim Levitsky Signed-off-by: David Woodhouse

mtd: Use BLOCK_NIL consistently in NFTL/INFTL

2009-06-27T08:22:10Z

Use BLOCK_NIL consistently rather than sometimes 0xffff and sometimes BLOCK_NIL. The semantic patch that finds this issue is below (http://www.emn.fr/x-info/coccinelle/). On the other hand, the changes were made by hand, in part because drivers/mtd/inftlcore.c contains dead code that causes spatch to ignore a relevant function. Specifically, the function INFTL_findwriteunit contains a do-while loop, but always takes a return that leaves the loop on the first iteration. // @r exists@ identifier f,C; @@ f(...) { ... return C; } @s@ identifier r.C; expression E; @@ @@ identifier r.f,r.C,I; expression s.E; @@ f(...) { <... ( I | - E + C ) ...> } // Signed-off-by: Julia Lawall Signed-off-by: David Woodhouse

[MTD] update internal API to support 64-bit device size

2008-12-10T13:37:21Z

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 Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse

[MTD] [INFTL] Fix infinite loop in INFTL_foldchain

2008-10-08T10:26:38Z

When iterating over a chain in reverse (oldest block first), this patch correctly marks the PUtable[] entry of the second to last erase block of a chain as BLOCK_NIL, regardless of whether or not it can format the last block successfully. Before, the second to last block was only marked as pointing to BLOCK_NIL if INFTL_formatblock() succeeded on the last block of the chain, which could potentially result in an infinite loop if the block was worn out and refused to format.

MTD/JFFS2: remove CVS keywords

2008-06-04T16:50:17Z

Once upon a time, the MTD repository was using CVS. This patch therefore removes all usages of the no longer updated CVS keywords from the MTD code. This also includes code that printed them to the user. Signed-off-by: Adrian Bunk Signed-off-by: David Woodhouse
