exfat_core.c - ffsReadFile - the goto err_out seem to leak a brelse().
same for ffsWriteFile.
-exfat_core.c - fs_sync(sb,0) all over the place looks fishy as hell.
-There's only one place that calls it with a non-zero argument.
-Randomly removing fs_sync() calls is *not* the right answer, especially
-if the removal then leaves a call to fs_set_vol_flags(VOL_CLEAN), as that

-The proper fix here is to go through and actually analyze how DELAYED_SYNC

-'true' is probably more correct. Also, it's likely that the one current

ffsTruncateFile - if (old_size <= new_size) {
That doesn't look right. How did it ever work? Are they relying on lazy
block allocation when actual writes happen? If nothing else, it never
does the 'fid->size = new_size' and do the inode update....
ffsSetAttr() is just dangling in the breeze, not wired up at all...

+exfat_core.c - The original code called fs_sync(sb,0) all over the place,
+with only one place that calls it with a non-zero argument. That's now been
+reversed, but a proper audit of sync and flush-to-disk is certainly needed.
+
+buf_sync(), sync_alloc_bitmap(), and FAT_sync() aren't actually used
+anyplace. This is probably related to the borked original implementatin
+of fs_sync() that didn't actually do anything either.
