[PATCH] ecryptfs: lookup: Don't check if mount_crypt_stat is NULL

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


mount_crypt_stat is assigned to
and mount_crypt_stat is not the first object in struct ecryptfs_sb_info.
mount_crypt_stat is therefore never NULL. At the same time, no crash
in ecryptfs_lookup() has been reported, and the lookup functions in
other file systems don't check if d_sb is NULL either.
Given that, remove the NULL check.
