Subject: xfs: remove xfs_iput_new
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ef35e9255d4ed12522e836fbcec861e7306d794a;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

xfs: remove xfs_iput_new

We never get an i_mode of 0 or a locked VFS inode until we pass in the
XFS_IGET_CREATE flag to xfs_iget, which makes xfs_iput_new equivalent to
xfs_iput for the only caller.  In addition to that xfs_nfs_get_inode
does not even need to lock the inode given that the generation never changes
for a life inode, so just pass a 0 lock_flags to xfs_iget and release
the inode using IRELE in the error path.
