  - mm/hugetlb: fix folio is still mapped when deleted Migration may be raced with fallocating hole.
    remove_inode_single_folio will unmap the folio if the folio is still mapped. However, it's called without     folio lock. If the folio is migrated and the mapped pte has been converted to migration entry,     folio_mapped() returns false, and won't unmap it. Due to extra refcount held by remove_inode_single_folio,     migration fails, restores migration entry to normal pte, and the folio is mapped again. As a result, we     triggered BUG in filemap_unaccount_folio. The log is as follows: BUG: Bad page cache in process hugetlb     pfn:156c00 page: refcount:515 mapcount:0 mapping:0000000099fef6e1 index:0x0 pfn:0x156c00 head: order:9     mapcount:1 entire_mapcount:1 nr_pages_mapped:0 pincount:0 aops:hugetlbfs_aops ino:dcc dentry     name(?):my_hugepage_file flags: 0x17ffffc00000c1(locked|waiters|head|node=0|zone=2|lastcpupid=0x1fffff)     page_type: f4(hugetlb) page dumped because: still mapped when deleted CPU: 1 UID: 0 PID: 395 Comm: hugetlb     Not tainted 6.17.0-rc5-00044-g7aac71907bde-dirty #484 NONE Hardware name: QEMU Ubuntu 24.04 PC (i440FX +     PIIX, 1996), BIOS 0.0.0 02/06/2015 Call Trace: <TASK> dump_stack_lvl+0x4f/0x70     filemap_unaccount_folio+0xc4/0x1c0 __filemap_remove_folio+0x38/0x1c0 filemap_remove_folio+0x41/0xd0     remove_inode_hugepages+0x142/0x250 hugetlbfs_fallocate+0x471/0x5a0 vfs_fallocate+0x149/0x380 Hold folio     lock before checking if the folio is mapped to avold race with migration.
