Hi, This patchset fixes a bug in Partition driver that created UDF logical partitions by using entire block device space and thus polluting protocol database with broken handles. v1->v2: - Followed Laszlo's suggestions to submit a proper patchset. Thanks! - As I'm still waiting for Ruiyu and Star to test this fix, I took advantage of it and did some code cleanups :-) v2->v3: - Followed Ruiyu's suggestions to improve code and add additional checks for ensuring a valid UDF file system and supported by current EDK2 UDF file system implementation. Also run Ecc.py to make sure the files I touched did not break EDK2 C Coding Style, as well as PatchCheck.py for mal-formed patches. v3->v4: - Change 2/2's title as suggested by Star. - Remove UDF_TAG_ID() and refactor out UDF_ENTITY_ID structure as suggested by Ruiyu. - Tested build with VS2015 toolchain. I've had a chance to test these changes with my 32GiB USB stick and formatted it on Windows 10 with `format` command. The UDF revisions I tested (by specifying it with "/R:revision") were 1.02, 1.50, 2.00, 2.01 (default) and 2.50. They all worked except the 2.50 revision which adds a Type 2 (Metadata) Partition and it's not supported by current EDK2 UDF implementation -- which handles only Type 1 (Physical) Partitions. The UDF 2.60 revision I tested with the usual `sudo mkudffs -b 512 --media-type=hd /dev/sdX` command in Linux. Remember, the *officially* supported revision is 2.60, however all revisions use the same volume structures as defined by ECMA 167 specification, and they usually differ from each other by means of new optional features, so that's why all those revisions worked with this implementation. Well, at least this what I understood when looking at the specifications. Please correct me if I'm wrong. Please, test building these changes in toolchains other than GCC and make sure they don't break the world :-) Thanks!
