[PATCH] fs: move generic stat response attr handling to vfs_getattr_nosec

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

 



generic_fillattr is an optional helper that isn't used by all
file systems, move handling purely based on inode flags to
vfs_getattr_nosec, which is common code.

This fixes setting this flag for file systems not using generic_fillattr
like xfs.
