Subject: xfs depends on exportfs

Hi,


I could not find a clue on the first try on why xfs needs exportfs.
The Kconfig says "select EXPORTFS if CONFIG_NFSD!=n", but there are no
occurrences of CONFIG_NFS* or CONFIG_EXP* in any of the files in fs/xfs/.
Did I miss something or this a superfluous line in Kconfig? Interestingly
tho, `modinfo xfs.ko` returns "exportfs", so I suppose it's somewhere, well
hidden. If so, where?


Regards,
Jan Engelhardt

xfs_export.c, find_exported_dentry.

XFS uses find_exported_dentry().

Hint: nm fs/xfs/xfs.ko | grep ' U .*exp'
