This causes the subsequent call to\nntfs_fs_free() to skip freeing the ntfs_mount_options structure.\n\nThis results in a kmemleak report:\n\n  unreferenced object 0xff1100015378b800 (size 32):\n    comm \"mount\", pid 582, jiffies 4294890685\n    hex dump (first 32 bytes):\n      00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  ................\n      00 00 00 00 00 00 00 00 ed ff ed ff 00 04 00 00  ................\n    backtrace (crc ed541d8c):\n      __kmalloc_cache_noprof+0x424/0x5a0\n      __ntfs_init_fs_context+0x47/0x590\n      alloc_fs_context+0x5d8/0x960\n      __x64_sys_fsopen+0xb1/0x190\n      do_syscall_64+0x50/0x1f0\n      entry_SYSCALL_64_after_hwframe+0x76/0x7e\n\nThis issue can be reproduced using the following commands:\n        fallocate -l 100M test.file\n        mount test.file /tmp/test\n\nSince sbi-\u003eoptions is duplicated from fc-\u003efs_private and does not\ndirectly use the memory allocated for fs_private, it is unnecessary to\nset fc-\u003efs_private to NULL.\n\nAdditionally, this patch simplifies the code by utilizing the helper\nfunction put_mount_options() instead of open-coding the cleanup logic."
