2010-09-15block, partition: add partition_meta_info to hd_structWill Drewry
I'm reposting this patch series as v4 since there have been no additional comments, and I cleaned up one extra bit of unneeded code (in 3/3). The patches are against Linus's tree: 2bfc96a127bc1cc94d26bfaa40159966064f9c8c (2.6.36-rc3). Would this patchset be suitable for inclusion in an mm branch? This changes adds a partition_meta_info struct which itself contains a union of structures that provide partition table specific metadata. This change leaves the union empty. The subsequent patch includes an implementation for CONFIG_EFI_PARTITION-based metadata. Signed-off-by: Will Drewry <wad@chromium.org> Signed-off-by: Jens Axboe <jaxboe@fusionio.com>

2010-05-21block: improve automatic native capacity unlockingTejun Heo
Currently, native capacity unlocking is initiated only when a recognized partition extends beyond the end of the disk. However, there are several other unhandled cases where truncated capacity can lead to misdetection of partitions. * Partition table is fully beyond EOD. * Partition table is partially beyond EOD (daisy chained ones). * Recognized partition starts beyond EOD. This patch updates generic partition check code such that all the above three cases are handled too. For the first two, @state tracks whether low level partition check code tried to read beyond EOD during partition scan and triggers native capacity unlocking accordingly. The third is now handled similarly to the original unlocking case. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Ben Hutchings <ben@decadent.org.uk> Acked-by: David S.

2010-05-21block: use struct parsed_partitions *state universally in partition check codeTejun Heo
Make the following changes to partition check code. * Add ->bdev to struct parsed_partitions. * Introduce read_part_sector() which is a simple wrapper around read_dev_sector() which takes struct parsed_partitions *state instead of @bdev. * For functions which used to take @state and @bdev, drop @bdev. For functions which used to take @bdev, replace it with @state. * While updating, drop superflous checks on NULL state/bdev in ldm.c. This cleans up the API a bit and enables better handling of IO errors during partition check as the generic partition check code now has much better visibility into what went wrong in the low level code paths.

2008-10-09block: replace @ext_minors with GENHD_FL_EXT_DEVTTejun Heo
With previous changes, it's meaningless to limit the number of partitions. Replace @ext_minors with GENHD_FL_EXT_DEVT such that setting the flag allows the disk to have maximum number of allowed partitions (only limited by the number of entries in parsed_partitions as determined by MAX_PART constant). This kills not-too-pretty alloc_disk_ext[_node]() functions and makes @minors parameter to alloc_disk[_node]() unnecessary. The parameter is left alone to avoid disturbing the users.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
