Subject: ceph: add ceph.dir.layout vxattr
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1f08f2b056ea6c2e12f4e95e88949a882a996208;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ceph: add ceph.dir.layout vxattr

This virtual xattr will only appear when there is a dir layout policy
set on the directory.  It can be set via setxattr and removed via
removexattr (implemented by the MDS).
