++ * Usage of this header:
++ * 1. define a static or hidden function __NC(NAME) - expands to __NAME_nocancel
++ * 2. if it is hidden, add the prototype to the appropiate header where NAME has
++ * it's prototype (guarded by _LIBC)
++ * 3. add a CANCELLABLE_SYSCALL(...) line at the end, this will create the function
++ * NAME (as weak) with enabled cancellation for NPTL (and later for new LT), for
++ * LT_OLD it will also create a strong_alias to __libc_NAME to be used in libpthread
++ * 4. if you need libc_hidden_(weak|def) line, use instead lt_libc_hidden, this will
++ * take care of the correct type, weak or strong depending on the THREADS type
++ * 5. If the implementation can't be done using CANCELLABLE_SYSCALL (like for fcntl)
++ * you need to manually add lt_strong_alias() line too, to optionally create the
++ * __libc_NAME alias
++ * 6. if functions are needed to implement __NC(NAME), that themselves are cancellable,
++ * decide how the cancellation should be solved, two variants are possible:
++ *  a. use the other function as __NC(FUNC), this way you access the non-cancellable
++ *  variant and provide by CANCELLABLE_SYSCALL(...) the dedicated cancellation for NAME.
++ *  be aware, that for this case __NC(FUNC) has to be hidden (not static)
++ *  b. use the other function with it's name (FUNC) and add LIBC_CANCEL_HANDLED(); at
++ *  the end of file with a comment telling us which function took care of the cancellation
++ * Note: LIBC_CANCEL_HANDLED() is noop on uClibc, glibc uses it only for tests, we use
++ * it only for "documentation".
++ *
++ * For now the use of this file is limited to libc, will expand later to support libpthread
++ * and librt as well.

+Subject: [PATCH 3/6] pread/pwrite: drop fallback funcs
+
+Linux has provided these functions since the 2.1.x era, so no need to
+keep these around.  We'd rather find out when things are missing (and
+fix that) than fall back to the unsafe hacks.

-pread/pwrite syscalls has been renamed to pread64/pwrite in 2.6 kernel.
-
-There was a fallback function using lseek for kernels who did not have
-this syscall (pre 2.1.60). This is broken in many ways.
-
-uclibc have been using the broken fallback due to they forgot to rename
-pread syscall.
-
-This got detected with git-1.7.11 which introduced threaded index-pack
-which broke in similar ways a windows (msys).
-
-This issue in uclibc have been reported upstream and fixed in git master
-so this patch does not need to be upstreamed. It might be an idea to
-backport it properly for 0.9.33 branch though.
