directory in which a lookup had been done with the status of the looked up
file. This corrupts some of the directory state.
Fixes: 5cf9dd55a0ec ("afs: Prospectively look up extra files when doing a
single lookup")
Increase the sizes of the volume ID to 64 bits and the vnode ID (inode
number equivalent) to 96 bits to allow the support of YFS.
This requires the iget comparator to check the vnode->fid rather than i_ino
and i_generation as i_ino is not sufficiently capacious. It also requires
this data to be
This is the commit that porting the perf for nds32.
1.Raw event:
The raw events start with 'r'.
Usage:
perf stat -e rXYZ ./app
X: the index of performance counter.
YZ: the index(convert to hexdecimal)

Remove unnecessary details of a broken callback, such as version, expiry
and type, from the afs_callback_break struct as they're not actually used
and make the list take more memory.

The ultimate goal is to create minimal isolated test binaries; in the
meantime we are using UML to provide the infrastructure to run tests, so
define an abstract way to configure and run tests that allow us to
change the context in which tests are built without affecting the user.

The perf call-graph option can trace the callchain
between functions. This commit add the perf callchain
for nds32. There are kerenl callchain and user callchain.
The kerenl callchain can trace the function in kernel
space. There are two type for user callchain. One for the
'optimize for size'
There two bitfield bug for perfomance counter
in bitfield.h:
PFM_CTL_offSEL1 21 --> 16
PFM_CTL_offSEL2 27 --> 22
This commit fix it.
