Summary
nilfs2: prevent kernel bug at submit_bh_wbc()
Details

In the Linux kernel, the following vulnerability has been resolved:

nilfs2: prevent kernel bug at submitbhwbc()

Fix a bug where nilfsgetblock() returns a successful status when searching and inserting the specified block both fail inconsistently. If this inconsistent behavior is not due to a previously fixed bug, then an unexpected race is occurring, so return a temporary error -EAGAIN instead.

This prevents callers such as _blockwritebeginint() from requesting a read into a buffer that is not mapped, which would cause the BUGON check for the BHMapped flag in submitbhwbc() to fail.
