f2fs: inode: fix to do sanity check on extent cache correctly

2023-05-17T09:53:59+00:00

commit 269d119481008cd725ce32553332593c0ecfc91c upstream.

In do_read_inode(), sanity check for extent cache should be called after
f2fs_init_read_extent_tree(), fix it.

f2fs: factor out victim_entry usage from general rb_tree use

2023-05-17T09:53:53+00:00

[ Upstream commit 043d2d00b44310f84c0593c63e51fae88c829cdd ]

Let's reduce the complexity of mixed use of rb_tree in victim_entry from
extent_cache and discard_cmd.

This should fix arm32 memory alignment issue caused by shared rb_entry.

[struct victim_entry]              [struct rb_entry]
[0] struct rb_node rb_node;        [0] struct rb_node rb_node;
                                       union {
                                         struct {
                                           unsigned int ofs;
                                           unsigned int len;
                                         };
[16] unsigned long long mtime;     [12] unsigned long long key;
                                       } __packed;
