This isn't ever used by VFS now, and it couldn't even work. Any FS that
uses the SECURITY_LSM_NATIVE_LABELS flag needs to also process the
value returned back from the LSM, so it needs to do its
security_sb_set_mnt_opts() call on its own anyway.

found by Syzbot and fuzzing. (Many of the bug fixes involve less-used
ext4 features such as fast_commit, inline_data and bigalloc.)
In addition, remove the writepage function for ext4, since the
medium-term plan is to remove ->writepage() entirely. (The VM doesn't
need or want writepage() for writeback, since it is fine with
->writepages() so long as ->migrate_folio() is implemented.)

Before the commit 461c3af045 ("ext4: Change handle_mount_opt() to use
fs_parameter") ext4 mount option journal_path did follow links in the
provided path.
Bring this behavior back by allowing to pass pathwalk flags to
fs_lookup_param().
Fixes: 461c3af045 ("ext4: Change handle_mount_opt() to use fs_parameter")

fill_super callback and a "bool reconf" instead. Also mark the function
static given that there are no users outside of super.c.

Change wording to say that messages are logged to the kernel log
buffer instead of to dmesg. dmesg is just one program that can
print the kernel log buffer.
