Description Robert Peterson 2010-05-06 18:08:35 UTC

Description of problem:
I was building a rhel6 kernel today from the srpm and noticed
some compiler warnings when btrfs was building.  They scrolled
off my screen pretty fast, but I got some of them:

fs/btrfs/ordered-data.c:136: warning: ‘prev’ may be used uninitialized in this function
fs/btrfs/ordered-data.c:136: note: ‘prev’ was declared here
fs/btrfs/ordered-data.c: In function ‘btrfs_lookup_first_ordered_extent’:
fs/btrfs/ordered-data.c:136: warning: ‘prev’ may be used uninitialized in this function
fs/btrfs/ordered-data.c:136: note: ‘prev’ was declared here
fs/btrfs/ordered-data.c: In function ‘btrfs_lookup_ordered_extent’:
fs/btrfs/ordered-data.c:136: warning: ‘prev’ may be used uninitialized in this f

Comment 3 RHEL Program Management 2010-07-15 14:47:25 UTC

This issue has been proposed when we are only considering blocker
issues in the current Red Hat Enterprise Linux release. It has
been denied for the current Red Hat Enterprise Linux release.

** If you would still like this issue considered for the current
release, ask your support representative to file as a blocker on
your behalf. Otherwise ask that it be considered for the next
Red Hat Enterprise Linux release. **
