2011-05-24mmc: remove redundant irq disablingJohn Ogness
There is no need to disable irq's when using the sg_copy_*_buffer() functions because those functions do that already. There are also no races for the mm_queue struct here that would require the irq's to be disabled before calling sg_copy_*_buffer().

2011-05-25mtd: omap2: mtd split nand_scan in ident and tailJan Weitzel
nand_scan calls nand_scan_tail and here we got a ecc.layout and calculate oobavail for this layout. After calling nand_scan, we change the layout pointer if OMAP_ECC_HAMMING_CODE_HW_ROMCODE is set. This results in not calcluated oobavail. Mountig as jffs2 is not possible. To fix that nand_scan has to split up in nand_scan_ident and nand_scan_tail setting ecc.layout between these calls. So nand_scan_tail calculates oobvail for the used layout. This is also done in serveral other platforms.

2011-05-25mtd: mtd_blkdevs: fix error path in blktrans_openArtem Bityutskiy
The 'blktrans_open()' does not handle possible '__get_mtd_device()' failures because it does not check the error code. Moreover, the 'dev->tr->open()' failures are not handled correctly because in this case the function just goes ahead and gets the mtd device, then returns an error. But Instead, it should _not_ try to get the mtd device, then it should put back the module and the kref. This patch fixes the issue. Note, I only compile-tested it. This patch was inspired by a bug report about a similar issue in 2.6.34 kernels sent by Mike Turner <admin@islandsoftware.co.uk> to the MTD mailing list: http://lists.infradead.org/pipermail/linux-mtd/2011-April/034980.html Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

2011-05-25mtd: nand: dynamic allocation of flash-based BBT structsBrian Norris
It is nicer to dynamically create our badblock patterns than to statically define them. The nand_create_default_bbt_descr() function does a sufficient job of handling various bad block scanning options for either flash-based or non-flash-based BBTs, so we might as well use the function for both cases.

2011-05-24ext4: only load buddy bitmap in ext4_trim_fs() when it is neededLukas Czerner
Currently we are loading buddy ext4_mb_load_buddy() for every block group we are going through in ext4_trim_fs() in many cases just to find out that there is not enough space to be bothered with. As Amir Goldstein suggested we can use bb_free information directly from ext4_group_info. This commit removes ext4_mb_load_buddy() from ext4_trim_fs() and rather get the ext4_group_info via ext4_get_group_info() and use the bb_free information directly from that. This avoids unnecessary call to load buddy in the case the group does not have enough free space to trim. Loading buddy is now moved to ext4_trim_all_free(). Tested by me with xfstests 251.
