    [ Analysis ]

    We believe that we have found a concurrency bug in the `fs/jfs` module     that results in a null pointer dereference. There is a closely related     issue which has been fixed:

    https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=d6c1b3599b2feb5c7291f5ac3a36     e5fa7cedb234

    ... but, unfortunately, the accepted patch appears to still be     susceptible to a null pointer dereference under some interleavings.

    To trigger the bug, we think that `JFS_SBI(ipbmap->i_sb)->bmap` is set     to NULL in `dbFreeBits` and then dereferenced in `jfs_ioc_trim`. This     bug manifests quite rarely under normal circumstances, but is     triggereable from a syz-program.
