Subject: xfs: pass the owner to xfs_symlink_write_target
X-Git-Tag: v6.10-rc1~87^2~63^2~1
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=ea8214c3195c2ed3a205dea42bbe7746712fc461;p=thirdparty%2Fkernel%2Flinux.git

xfs: pass the owner to xfs_symlink_write_target

Require callers of xfs_symlink_write_target to pass the owner number
explicitly.  This sets us up for online repair to be able to write a
remote symlink target to sc->tempip with sc->ip's inumber in the block
heaader.
