kconfig: allow multiple inclusion of the same file

Allow 'source'ing the same file from multiple places (eg. from
different files, and/or under different conditions).

To avoid circular inclusion, scan the source-ancestry of the

8 years agokconfig: Avoid buffer underrun in choice input
Ben Hutchings [Sat, 19 Mar 2011 04:26:10 +0000]
kconfig: Avoid buffer underrun in choice input

commit 40aee729b350672c2550640622416a855e27938f ('kconfig: fix default
value for choice input') fixed some cases where kconfig would select
the wrong option from a choice with a single valid option and thus
enter an infinite loop.

However, this broke the test for user input of the form 'N?', because
when kconfig selects the single valid option the input is zero-length
and the test will read the byte before the input buffer.  If this
happens to contain '?' (as it will in a mips build on Debian unstable
today) then kconfig again enters an infinite loop.

fs: don't use igrab() while holding i_lock

Fix the incorrect use of igrab() inside the i_lock in NFS and Ceph‥

If we are already holding the i_lock, we have a reference to the
inode so we can safely use ihold() to gain an extra reference. This
avoids hangs due to lock recursion on the i_lock now that the
inode_lock is gone and igrab() uses the i_lock itself.

2) Use the preflow handler, which is called from the fasteoi core code
