X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2729423cf2ef3ac51d040f24a5ddd84c1b2acc70;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

xfs: Fix xfs_swap_extents() after removal of xfs_flushinval_pages()

Commit fb59581404ab7ec5075299065c22cb211a9262a9 removed
xfs_flushinval_pages() and changed its callers to use
filemap_write_and_wait() and  truncate_pagecache_range() directly.

But in xfs_swap_extents() this change accidental switched the argument
for 'tip' to 'ip'. This patch switches it back to 'tip'
