[PATCH v2 00/25] erofs: patchset addressing Christoph's comments

[Gao Xiang]

Hi,

This patchset is based on the following patch by Pratik Shinde,
https://lore.kernel.org/linux-erofs/20190830095615.10995-1-pratikshinde320@gmail.com/

All patches addressing Christoph's comments on v6, which are trivial,
most deleted code are from erofs specific fault injection, which was
followed f2fs and previously discussed in earlier topic [1], but
let's follow what Christoph's said now.

Comments and suggestions are welcome...

[1] https://lore.kernel.org/r/1eed1e6b-f95e-aa8e-c3e7-e9870401ee23@kernel.org/

changes since v1:
 - leave some comments near the numbers to indicate where they are stored;
 - avoid a u8 cast;
 - use erofs_{err,info,dbg} and print sb->s_id as a prefix before
   the actual message;
 - add a on-disk title in erofs_fs.h
 - use feature_{compat,incompat} rather than features and requirements;
 - suggestions on erofs_grab_bio:
   https://lore.kernel.org/r/20190902122016.GL15931@infradead.org/
 - use compact/extended instead of erofs_inode_v1/v2 and
   i_format instead of i_advise;
 - avoid chained if/else if/else if statements in erofs_read_inode;
 - avoid erofs_vmap/vunmap wrappers;
 - use read_cache_page_gfp for erofs_get_meta_page;
