Date: Tue, 13 Mar 2012 02:46:25 -0700 From: Stephen Boyd <sboyd@...eaurora.org> To: linux-kernel@...r.kernel.org Cc: <linux-fsdevel@...r.kernel.org>, Greg Kroah-Hartman <gregkh@...uxfoundation.org>, Al Viro <viro@...iv.linux.org.uk>, Julia Lawall <Julia.Lawall@...6.fr>, Andrew Morton <akpm@...ux-foundation.org> Subject: [PATCHv2 0/3] Introduce simple_open() I noticed that if I want to tweak debugfs file ops I need to copy the implementation of default_open() in fs/debugfs/file.c. I went to look for an exported function that would be common across all debugfs users but I couldn't find any. This patchset moves default_open() to libfs so that other filesystems can use it (although almost 99% of users are debugfs clients). Andrew has picked up the first patch but I'm including it here for completeness. This is based on linux-next at next-20120302 Changes since v1: * Fixed coccinelle script * Included mega patch to move all current users Cc: <linux-fsdevel@...r.kernel.org> Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org> Cc: Al Viro <viro@...iv.linux.org.uk> Cc: Julia Lawall <Julia.Lawall@...6.fr> Cc: Andrew Morton <akpm@...ux-foundation.org> Stephen Boyd (3): libfs: Add simple_open() coccinelle: semantic patch for simple_open() simple_open: Automatically convert to simple_open() arch/arm/mach-msm/smd_debug.c | 8 +---- arch/arm/plat-mxc/audmux-v2.c | 8 +---- arch/x86/kernel/kdebugfs.c | 9 +---- drivers/acpi/ec_sys.c | 8 +---- drivers/base/regmap/regmap-debugfs.c | 12 ++----- drivers/bluetooth/btmrvl_debugfs.c | 26 ++++++-------- drivers/char/virtio_console.c | 8 +---- drivers/dma/coh901318.c | 9 +---- drivers/gpu/drm/i915/i915_debugfs.c | 14 ++------ drivers/hid/hid-picolcd.c | 22 ++---------- drivers/hid/hid-wiimote-debug.c | 8 +---- drivers/idle/i7300_idle.c | 8 +---- drivers/iommu/omap-iommu-debug.c | 10 ++---- drivers/mfd/aat2870-core.c | 9 +---- drivers/mfd/ab3100-core.c | 8 +---- drivers/misc/ibmasm/ibmasmfs.c | 8 +---- drivers/mtd/ubi/debug.c | 10 +----- drivers/net/caif/caif_spi.c | 10 ++---- drivers/net/ethernet/chelsio/cxgb4/cxgb4_main.c | 12 +------ drivers/net/wimax/i2400m/debugfs.c | 15 ++------ drivers/net/wireless/ath/ath5k/debug.c | 23 +++++------- drivers/net/wireless/ath/ath6kl/debug.c | 44 ++++++++++------------- drivers/net/wireless/ath/ath9k/debug.c | 37 +++++++++---------- drivers/net/wireless/ath/ath9k/dfs_debug.c | 9 +---- drivers/net/wireless/ath/ath9k/htc_drv_debug.c | 26 ++++++-------- drivers/net/wireless/ath/ath9k/rc.c | 8 +---- drivers/net/wireless/ath/carl9170/debug.c | 7 +--- drivers/net/wireless/b43/debugfs.c | 8 +---- drivers/net/wireless/b43legacy/debugfs.c | 8 +---- drivers/net/wireless/iwlegacy/3945-rs.c | 8 +---- drivers/net/wireless/iwlegacy/4965-rs.c | 12 ++----- drivers/net/wireless/iwlegacy/debug.c | 12 ++----- drivers/net/wireless/iwlwifi/iwl-agn-rs.c | 11 ++---- drivers/net/wireless/iwlwifi/iwl-debugfs.c | 12 ++----- drivers/net/wireless/iwlwifi/iwl-trans-pcie.c | 12 ++----- drivers/net/wireless/iwmc3200wifi/debugfs.c | 14 +++----- drivers/net/wireless/iwmc3200wifi/sdio.c | 9 +---- drivers/net/wireless/libertas/debugfs.c | 8 +---- drivers/net/wireless/mwifiex/debugfs.c | 18 ++-------- drivers/net/wireless/wl1251/debugfs.c | 10 ++---- drivers/net/wireless/wl12xx/debugfs.c | 34 ++++++++---------- drivers/oprofile/oprofilefs.c | 14 ++------ drivers/remoteproc/remoteproc_debugfs.c | 13 ++----- drivers/scsi/lpfc/lpfc_debugfs.c | 9 +---- drivers/spi/spi-dw.c | 8 +---- drivers/tty/serial/mfd.c | 9 ++--- drivers/tty/serial/pch_uart.c | 8 ++--- drivers/usb/core/inode.c | 10 +----- drivers/usb/host/ehci-dbg.c | 9 +---- drivers/uwb/uwb-debug.c | 9 +---- fs/debugfs/file.c | 14 ++------ fs/dlm/debug_fs.c | 12 +------ fs/libfs.c | 8 +++++ fs/pstore/inode.c | 8 +---- include/linux/fs.h | 1 + kernel/trace/blktrace.c | 18 ++-------- net/mac80211/debugfs.c | 16 +++------ net/wireless/debugfs.c | 8 +---- scripts/coccinelle/api/simple_open.cocci | 34 ++++++++++++++++++ sound/soc/soc-core.c | 8 +---- sound/soc/soc-dapm.c | 16 ++------- 61 files changed, 210 insertions(+), 574 deletions(-) create mode 100644 scripts/coccinelle/api/simple_open.cocci -- Sent by an employee of the Qualcomm Innovation Center, Inc.
