Hi,
I'm sending three "sleeping function called from invalid context" bug
fixes that I had on my TODO for a while. All of them are ceph_buffer_put
related, and all the fixes follow the same pattern: delay the operation
until the ci->i_ceph_lock is released.
The first patch simply allows ceph_buffer_put to receive a NULL buffer so
that the NULL check doesn't need to be performed in all the other patches.
IOW, it's not really required, just convenient.
(Note: maybe these patches should all be tagged for stable.)
Luis Henriques (4):
libceph: allow ceph_buffer_put() to receive a NULL ceph_buffer
ceph: fix buffer free while holding i_ceph_lock in __ceph_setxattr()
ceph: fix buffer free while holding i_ceph_lock in
__ceph_build_xattrs_blob()
ceph: fix buffer free while holding i_ceph_lock in fill_inode()
