[PATCH v2 00/22] staging: erofs: updates according to erofs-outofstaging v4

[Gao Xiang]

changes from v1:
 (mainly address comments from Chao:)
  - keep EROFS_IO_MAX_RETRIES_NOFAIL;
  - add a new patch "drop __GFP_NOFAIL for managed inode";
  - kill a redundant NULL check in "__stagingpage_alloc";
  - add some description in document about "use_vmap";
  - rearrange erofs_vmap of "staging: erofs: kill CONFIG_EROFS_FS_USE_VM_MAP_RAM";
 - combine two similar patches about "cleaning up internal.h"
   since they rearrange the same file...

----8<----

This patchset includes all meaningful modifications till now according
to erofs-outofstaging v4:
https://lore.kernel.org/linux-fsdevel/20190725095658.155779-1-gaoxiang25@huawei.com/

Some empty lines which were add or delete are not included in this
patchset, I will send erofs-outofstaging v5 later in order to keep
main code bit-for-bit identical with this staging patchset.

Thanks,
Gao Xiang
