Subject: vfs: inline new_inode_pseudo() and de-staticize alloc_inode()
X-Git-Tag: v6.15-rc1~254^2~20
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1479be62582dbd2078390ef609f8f5ef351c15e8;p=thirdparty%2Fkernel%2Flinux.git

vfs: inline new_inode_pseudo() and de-staticize alloc_inode()

The former is a no-op wrapper with the same argument.

I left it in place to not lose the information who needs it -- one day
"pseudo" inodes may start differing from what alloc_inode() returns.

In the meantime no point taking a detour.
