fs: introduce f_op->mmap_capabilities for nommu mmap support

2015-01-20T21:02:58Z

Since "BDI: Provide backing device capability information [try #3]" the backing_dev_info structure also provides flags for the kind of mmap operation available in a nommu environment, which is entirely unrelated to it's original purpose. Introduce a new nommu-only file operation to provide this information to the nommu mmap code instead. Splitting this from the backing_dev_info structure allows to remove lots of backing_dev_info instance that aren't otherwise needed, and entirely gets rid of the concept of providing a backing_dev_info for a character device. It also removes the need for the mtd_inodefs filesystem. Signed-off-by: Christoph Hellwig Reviewed-by: Tejun Heo Acked-by: Brian Norris Signed-off-by: Jens Axboe

mtd: Account for BBT blocks when a partition is being allocated

2014-07-09T01:38:29Z

With the introduction of mtd_block_isreserved(), it's now possible to fix the bad and reserved block distribution exposed by ecc_stats, instead of accounting all the bad or reserved blocks as 'bad'. Signed-off-by: Ezequiel Garcia Tested-by: Pekon Gupta Signed-off-by: Brian Norris

mtd: Introduce mtd_block_isreserved()

2014-07-09T01:38:16Z

In addition to mtd_block_isbad(), which checks if a block is bad or reserved, it's needed to check if a block is reserved only (but not bad). This commit adds an MTD interface for it, in a similar fashion to mtd_block_isbad(). While here, fix mtd_block_isbad() so the out-of-bounds checking is done before the callback check.

mtd: add 'const' qualifier to a couple of register functions

2013-04-05T12:02:16Z

'mtd_device_parse_register()' and 'parse_mtd_partitions()' functions accept a an array of character pointers. These functions modify neither the pointers nor the characters they point to. The characters are actually names of the MTD parsers. At the moment, the argument type is 'const char **', which means that only the names of the parsers are constant. Let's turn the argument type into 'const char * const *', which means that both names and the pointers which point to them are constant. Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse
