Hi Linus,
Could you consider this pull request for 5.17-rc1?
In this cycle, tail-packing data inline for compressed files is now
supported so that tail pcluster can be stored and read together with
inode metadata in order to save data I/O and storage space.
In addition to that, to prepare for the upcoming subpage, folio and
fscache features, we also introduce meta buffers to get rid of
erofs_get_meta_page() since it was too close to the page itself.
Besides, in order to show supported kernel features and control sync
decompression strategy. new sysfs nodes are introduced in this
cycle as well.
All commits have been in -next and no merge conflicts.
Thanks,
Gao Xiang
