+Subject: pread/pwrite: backport fix
+
+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.

+Subject: pread/pwrite: backport fix
+
+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.

+Subject: pread/pwrite: backport fix
+
+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.

+Subject: pread/pwrite: backport fix
+
+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.

+Subject: pread/pwrite: backport fix
+
+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.
