Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull VFS updates from Al Viro, Misc cleanups all over the place, mainly wrt /proc interfaces (switch create_proc_entry to proc_create(), get rid of the deprecated create_proc_read_entry() in favor of using proc_create_data() and seq_file etc). 7kloc removed. * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (204 commits) don't bother with deferred freeing of fdtables proc: Move non-public stuff from linux/proc_fs.h to fs/proc/internal.h proc: Make the PROC_I() and PDE() macros internal to procfs proc: Supply a function to remove a proc entry by PDE take cgroup_open() and cpuset_open() to fs/proc/base.c ppc: Clean up scanlog ppc: Clean up rtas_flash driver somewhat hostap: proc: Use remove_proc_subtree() drm: proc: Use remove_proc_subtree() drm: proc: Use minor->index to label things, not PDE->name drm: Constify drm_proc_list[] zoran: Don't print proc_dir_entry data in debug reiserfs: Don't access the proc_dir_entry in r_open(), r_start() r_show() proc: Supply an accessor for getting the data from a PDE's parent airo: Use remove_proc_subtree() rtl8192u: Don't need to save device proc dir PDE rtl8187se: Use a dir under /proc/net/r8180/ proc: Add proc_mkdir_data() proc: Move some bits from linux/proc_fs.h to linux/{of.h,signal.h,tty.h} proc: Move PDE_NET() to fs/proc/proc_net.c ...

- * How to be a proc read function
- * ------------------------------
- * Prototype:
- * int f(char *buffer, char **start, off_t offset,
- * int count, int *peof, void *dat)
- *
- * Assume that the buffer is "count" bytes in size.
- *
- * If you know you have supplied all the data you
- * have, set *peof.
- *
- * You have three ways to return data:
- * 0) Leave *start = NULL. (This is the default.)
- * Put the data of the requested offset at that
- * offset within the buffer. Return the number (n)
- * of bytes there are from the beginning of the
- * buffer up to the last byte of data. If the
- * number of supplied bytes (= n - offset) is
- * greater than zero and you didn't signal eof
- * and the reader is prepared to take more data
- * you will be called again with the requested
- * offset advanced by the number of bytes
- * absorbed. This interface is useful for files
- * no larger than the buffer.
- * 1) Set *start = an unsigned long value less than
- * the buffer address but greater than zero.
- * Put the data of the requested offset at the
- * beginning of the buffer. Return the number of
- * bytes of data placed there. If this number is
- * greater than zero and you didn't signal eof
- * and the reader is prepared to take more data
- * you will be called again with the requested
- * offset advanced by *start. This interface is
- * useful when you have a large file consisting
- * of a series of blocks which you want to count
- * and return as wholes.
- * (Hack by Paul.Russell@rustcorp.com.au)
- * 2) Set *start = an address within the buffer.
- * Put the data of the requested offset at *start.
- * Return the number of bytes of data placed there.
- * If this number is greater than zero and you
- * didn't signal eof and the reader is prepared to
- * take more data you will be called again with the
- * requested offset advanced by the number of bytes

- * have, set *peof.
- *
- * You have three ways to return data:
- * 0) Leave *start = NULL. (This is the default.)
- * Put the data of the requested offset at that
- * offset within the buffer. Return the number (n)
- * of bytes there are from the beginning of the
- * buffer up to the last byte of data. If the
- * number of supplied bytes (= n - offset) is
- * greater than zero and you didn't signal eof
- * and the reader is prepared to take more data
- * you will be called again with the requested
- * offset advanced by the number of bytes
- * absorbed. This interface is useful for files
- * no larger than the buffer.
- * 1) Set *start = an unsigned long value less than
- * the buffer address but greater than zero.
- * Put the data of the requested offset at the
- * beginning of the buffer. Return the number of
- * bytes of data placed there. If this number is
- * greater than zero and you didn't signal eof
- * and the reader is prepared to take more data
- * you will be called again with the requested
- * offset advanced by *start. This interface is
- * useful when you have a large file consisting
- * of a series of blocks which you want to count
- * and return as wholes.
- * (Hack by Paul.Russell@rustcorp.com.au)
- * 2) Set *start = an address within the buffer.
- * Put the data of the requested offset at *start.
- * Return the number of bytes of data placed there.
- * If this number is greater than zero and you

- generic_file_write() is only appropriate for filesystems that are not seeking to optimize performance and want
- something simple that works. It is not for serious use by general purpose filesystems, excepting the one that it was
- written for (ext2/3). This is for several reasons:
-
- * It has no understanding of any filesystem specific optimizations.
-
- * It enters the filesystem repeatedly for each page that is written.
-
- * It depends on reiserfs_get_block() function which if implemented by reiserfs performs costly search_by_key
- * operation for each page it is supplied with. By contrast reiserfs_file_write() feeds as much as possible at a time
- * to reiserfs which allows for fewer tree traversals.
-
- * Each indirect pointer insertion takes a lot of cpu, because it involves memory moves inside of blocks.
-
- * Asking the block allocation code for blocks one at a time is slightly less efficient.
-
- All of these reasons for not using only generic file write were understood back when reiserfs was first miscoded to
- use it, but we were in a hurry to make code freeze, and so it couldn't be revised then. This new code should make
- things right finally.
-
