      [PATCH] wan/sdla_chdlc.c oops fix · 1934cd65
      Eric Sandeen authored
      This "warning fix" bug report is actually an OOPS bugfix.

      [PATCH] fs/locks.c: eliminate locks_unlock_delete · 803e701d
      Matthew Wilcox authored
      locks_unlock_delete is buggy in a couple of different ways (previously
      reported by Brian Dixon). Rather than fix it, this patch simply deletes
      it and uses the normal posix file locking mechanisms to remove all locks
      in locks_remove_posix instead.

      [PATCH] docbook: parportbook dependencies and do_cmd · 1fe581d8
      Sam Ravnborg authored
      o Corrected dependencies for parportbook
      o Introduced do_cmd, thus adhering to KBUILD_VERBOSE and make -s

      [PATCH] kbuild: Add new define do_cmd · 05e7c453
      Sam Ravnborg authored
      do_cmd is a nice shorthand when creating rules that in one line
      shall adhere to KBUILD_VERBOSE and make -s.
      So far the only user is (will be) the docbook makefile

      [PATCH] remove acct arg from do_munmap · a5271c10
      Hugh Dickins authored
      An acct flag was added to do_munmap, true everywhere but in mremap's
      move_vma: instead of updating the arch and driver sources, revert that
      that change and temporarily mask VM_ACCOUNT around that one do_munmap.
      
      Also, noticed that do_mremap fails needlessly if both shrinking _and_
      moving a mapping: update old_len to pass vm area boundaries test.

      [PATCH] shmem_file_setup when MAP_NORESERVE · d9acf5fe
      Hugh Dickins authored
      If we support mmap MAP_NORESERVE, we should support it on shared
      anonymous objects: too bad that needs a few changes.  do_mmap_pgoff pass
      VM_ACCOUNT (or not) down to shmem_file_setup, flag stored into shmem
      info, for use by shmem_delete_inode later.  Also removed a harmless but
      pointless call to shmem_truncate.

      [PATCH] fix shared and private accounting · e054680b
      Hugh Dickins authored
      do_mmap_pgoff's (file == NULL) check was incorrect: it caused shared
      MAP_ANONYMOUS objects to be counted twice (again in shmem_file_setup),
      and again on fork(); whereas the equivalent shared /dev/zero objects
      were correctly counted.  Conversely, a private readonly file mapping
      was (correctly) not counted, but still not counted when mprotected to
      writable: mprotect_fixup had pointless "charged = 0" changes, now it
      does vm_enough_memory checking when private is first made writable
      (but later we may want to refine behaviour on a noreserve mapping).
      
      Also changed correct (flags & MAP_SHARED) test in do_mmap_pgoff to
      equivalent (vm_flags & VM_SHARED) test: because do_mmap_pgoff is
      dealing with vm_flags rather than the input flags by that stage.

      [PATCH] remove unhelpful vm_unacct_vma · 3f7583d3
      Hugh Dickins authored
      Remove vm_unacct_vma function: it's only used in one place,
      which can do it better by using vm_unacct_memory directly.

      [PATCH] mmap MAP_NORESERVE not in vm_flags · feb32a85
      Hugh Dickins authored
      do_mmap_pgoff clears MAP_NORESERVE from vm_flags when VM accounts
      strictly: but it's not in vm_flags, it's in flags (and tested there).

      [PATCH] mremap MAP_NORESERVE not in flags · 4b07a3c5
      Hugh Dickins authored
      There is no point in do_mremap clearing MAP_NORESERVE from its flags:
      it has already validated that only the MREMAP_ flags can be set,
      and it has no use for MAP_NORESERVE in the code that follows anyway.

      [PATCH] SHMEM_MAX_BYTES overflow checking · 36372380
      Hugh Dickins authored
      shmem_notify_change and shmem_file_write be careful about overflowingly
      large loff_t before shifting it into unsigned long for vm_enough_memory.
      Rename SHMEM_MAX_BLOCKS to SHMEM_MAX_INDEX (to avoid confusion with
      512-byte blocks), define SHMEM_MAX_BYTES from it.
      
      But 2.5 vmtruncate lacked the s_maxbytes error handling which
      shmem_notify_change now expects: bring it in from the -dj tree.
      shmem_file_write error handling needs a closer look later on.

      [PATCH] shmem_file_write rounding VM_ACCT · 477436ba
      Hugh Dickins authored
      Repeated overnight kernel builds in tmpfs showed insane Committed_AS
      by morning.  The main bug was that shmem_file_write was passing
      (newsize-oldsize)>>PAGE_SHIFT to vm_enough_memory, but it has to be
      ((newsize>>PAGE_SHIFT)-(oldsize>>PAGE_SHIFT)) - imagine 1k writes.
      
      But actually, if we're going to do strict accounting, then we should
      round up to next page not down - use VM_ACCT macro throughout (needs
      unusual mix of PAGE_CACHE_SIZE with PAGE_SHIFT); and must count one
      page for a long symlink.
