Xiang has submitted several patches as below to fix compiling error on -next
tree, could you consider to merge those temporary fixes into -next after merging
staging-next's updates, and reenable CONFIG_EROFS_FS for further integrity
compiling and test?
staging: erofs: fix superblock/inode flags (MS_RDONLY -> SB_RDONLY, S_NOATIME)
https://lists.ozlabs.org/pipermail/linux-erofs/2018-July/000282.html
staging: erofs: remove RADIX_TREE_EXCEPTIONAL_{ENTRY, SHIFT}
https://lists.ozlabs.org/pipermail/linux-erofs/2018-July/000283.html
staging: erofs: update .mount and .remount_sb
https://lists.ozlabs.org/pipermail/linux-erofs/2018-July/000285.html
BTW, for this condition that erofs was not covered by some common vfs stuff
changes in other one's tree, who should take care of those missing fixes during
coming next merge window?
Thanks,
