"value": "In the Linux kernel, the following vulnerability has been resolved:\n\next4: fix fast commit wait/wake bit mapping on 64-bit\n\nOn 64-bit, ext4 dynamic inode states live in the upper half of i_flags,\nand ext4_test_inode_state() applies the corresponding +32 offset.\n\nThe fast-commit wait and wake paths open-coded the wait key with the raw\nEXT4_STATE_* value. Add small helpers for the state wait word and bit,\nand use them for the FC_COMMITTING and FC_FLUSHING_DATA waits so the wait\nkey follows the same mapping as the state helpers."
