2019-12-08erofs: update documentationGao Xiang
Some on-disk structures, fields have been renamed in v5.4, the corresponding document should be updated as well. Also fix misrespresentation of file time and words about fixed-sized output compression, data inline, etc. Link: https://lore.kernel.org/r/20191207025509.6614-1-hsiangkao@aol.com/ Signed-off-by: Gao Xiang <gaoxiang25@huawei.com>
2019-09-05erofs: kill use_vmap module parameterGao Xiang
As Christoph said [1], "vm_map_ram is supposed to generally behave better. So if it doesn't please report that that to the arch maintainer and linux-mm so that they can look into the issue. Having user make choices of deep down kernel internals is just a horrible interface. Please talk to maintainers of other bits of the kernel if you see issues and / or need enhancements. " Let's redo the previous conclusion and kill the vmap approach.

2019-09-05erofs: kill all erofs specific fault injectionGao Xiang
As Christoph suggested [1], "Please just use plain kmalloc everywhere and let the normal kernel error injection code take care of injeting any errors."

2019-08-24erofs: move erofs out of stagingGao Xiang
EROFS filesystem has been merged into linux-staging for a year. EROFS is designed to be a better solution of saving extra storage space with guaranteed end-to-end performance for read-only files with the help of reduced metadata, fixed-sized output compression and decompression inplace technologies. In the past year, EROFS was greatly improved by many people as a staging driver, self-tested, betaed by a large number of our internal users, successfully applied to almost all in-service HUAWEI smartphones as the part of EMUI 9.1 and proven to be stable enough to be moved out of staging. EROFS is a self-contained filesystem driver. Although there are still some TODOs to be more generic, we have a dedicated team actively keeping on working on EROFS in order to make it better with the evolution of Linux kernel as the other in-kernel filesystems. As Pavel suggested, it's better to do as one commit since git can do moves and all histories will be saved in this way. Let's promote it from staging and enhance it more actively as a "real" part of kernel for more wider scenarios!
