jffs2: Erase pending blocks in GC pass, avoid invalid -EIO return jffs2_garbage_collect_pass() would previously return -EAGAIN if it couldn't find anything to garbage collect from, and there were blocks on the erase_pending_list. If the blocks were actually in the process of being erased, though, then they wouldn't be on that list. Check for nr_erasing_blocks being non-zero instead. Fix jffs2_reserve_space() to wait for the in-progress erases to complete, when jffs2_garbage_collect_pass() returns -EAGAIN. And fix jffs2_erase_succeeded() to actually wake up the erase_wait wq that jffs2_reserve_space() is now using. Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

jffs2: Fix corruption when flash erase/write failure 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(). This is bad as jffs2_erase_failed() will also move the block to the bad_list, but is now moving the wrong block, causing FS corruption.

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

[JFFS2] Fix free space leak with in-band cleanmarkers We were accounting for the cleanmarker by calling jffs2_link_node_ref() (without locking!), which adjusted both superblock and per-eraseblock accounting, subtracting the size of the cleanmarker from {jeb,c}->free_size and adding it to {jeb,c}->used_size. But only _then_ were we adding the size of the newly-erased block back to the superblock counts, and we were adding each of jeb->{free,used}_size to the corresponding superblock counts. Thus, the size of the cleanmarker was effectively subtracted from the superblock's free_size _twice_. Fix this, by always adding a full eraseblock size to c->free_size when we've erased a block. And call jffs2_link_node_ref() under the proper lock, while we're at it. Thanks to Alexander Yurchenko and/or Damir Shayhutdinov for (almost) pinpointing the problem.

[JFFS2] Reduce time for which erase_free_sem is held during erase. With current desing erase_free_sem is locked every time the flash block is being erased. For NOR flashes - ~1 second is needed to erase single flash block. In the worst case scenario erase_free_sem may be locked for a couple of seconds when the number of blocks is being erased (e.g. after large file was removed). When erase_free_sem is locked all read/write operations for given JFFS2 partition are locked too - in effect from time to time access to the JFFS2 partition is locked for a number of seconds. This fix makes critical section in flash erasing procedure shorter - now erase_free_sem is locked around erase_completion_lock spinlock only.
