Subject: [PATCH 0/5] pstore: Initial use of cleanup.h

Hi,

Mostly as practice for myself, I rewrote a bunch of the error handling
paths in pstore to use the new cleanup.h routines. Notably, this meant
adding a DEFINE_FREE() for struct inode. Notably, I'm enjoying this
part: "44 insertions(+), 65 deletions(-)"

It also passes basic testing. :)

Kees Cook (5):
  pstore: inode: Convert kfree() usage to __free(kfree)
  pstore: inode: Convert mutex usage to guard(mutex)
  fs: Add DEFINE_FREE for struct inode
  pstore: inode: Use __free(iput) for inode allocations
  pstore: inode: Use cleanup.h for struct pstore_private
