Hi All, My appdata partition could not be mounted or where the partition was not able to be used. Anyone can help me to find out the root cause of this. What are the possibilities of this ubifs corruption. Any patched are available to fix this issue. I am using the kernel version-30.3.5 Any kernel patches are available to solve this issue...?? Error logs: [ 1.797141] UBI error: ubi_io_read: error -74 (ECC error) while reading 253952 bytes from PEB 445:8192, read 253952 bytes [ 1.808274] UBIFS error (pid 491): ubifs_scan: corrupt empty space at LEB 489:233760 [ 1.816037] UBIFS error (pid 491): ubifs_scanned_corruption: corruption at LEB 489:233760 [ 1.828660] UBIFS error (pid 491): ubifs_scan: LEB 489 scanning failed [ 1.835215] UBIFS warning (pid 491): ubifs_ro_mode: switched to read-only mode, error -117 [ 1.843502] UBIFS error (pid 491): make_reservation: cannot reserve 58 bytes in jhead 2, error -117 [ 1.852569] UBIFS error (pid 491): do_writepage: cannot write page 0 of inode 76584, error -117 dpkg: error: unable to sync new file '/var/lib/dpkg/arch-new': Structure needs cleaning Best regards Raghavan Anurag RBEI/ETW1 Tel. +91(422)667-4001 | Mobil 9986968950

[alsa-devel] [PATCH] ASoC: pxa2xx-ac97: Remove unused DAI ID defines
by Lars-Peter Clausen 05 Jan '17

05 Jan '17

The DAI ID defines are back from the time when DAIs were referenced by a numerical ID. These days a string is used instead and the defines are unused. The last user of these defines was removed in commit f0fba2ad1b6b ("ASoC: multi-component - ASoC Multi-Component Support"). So remove the defines as well. This also means the pxa2xx-ac97.h file no longer has any content and can be removed.

[alsa-devel] [PATCH] Revert "ALSA: firewire-lib: change structure member with proper type"
by Takashi Sakamoto 05 Jan '17

05 Jan '17

This reverts commit 6b7e95d1336b9eb0d4c6db190ce756480496bd13. This commit is based on a concern about value of the given parameter. It's expected to be ORed value with some enumeration-constants, thus often it can not be one of the enumeration-constants. I understood that this is out of specification and causes implementation-dependent issues. In C language specification, enumerated type can be interpreted as an integer type, in which all of enumeration-constants in corresponding enumerator-list can be stored. Implementations can select one of char, signed int and unsigned int as its type, and this selection is implementation-dependent. In GCC, a signed integer is selected when at least one of enumeration-constants has negative value, else an unsigned integer is selected. This behaviour can be switched by -fshort-enums to short type. Anyway, the type can be decided after scanning all of enumeration-constants. Totally, there's no rules to constrain the value of enumerated type to be one of enumeration-constants. In short, in enumerated type, decision of actual type for the type is the most important and enumeration-constants are just used for the decision, thus it's permitted to have an integer value in a range of enumeration-constants. In our case, actual type for the type is currently deterministic to be either char or unsigned int. Under GCC, it's unsigned int. --- sound/firewire/amdtp-stream.c | 2 +- sound/firewire/amdtp-stream.h | 4 ++-- 2 files changed, 3 insertions(+), 3 deletions(-) diff --git a/sound/firewire/amdtp-stream.c b/sound/firewire/amdtp-stream.c index 8ce93cd..00060c4 100644 --- a/sound/firewire/amdtp-stream.c +++ b/sound/firewire/amdtp-stream.c @@ -69,7 +69,7 @@ static void pcm_period_tasklet(unsigned long data); * @protocol_size: the size to allocate newly for protocol */ int amdtp_stream_init(struct amdtp_stream *s, struct fw_unit *unit, - enum amdtp_stream_direction dir, int flags, + enum amdtp_stream_direction dir, enum cip_flags flags, unsigned int fmt, amdtp_stream_process_data_blocks_t process_data_blocks, unsigned int protocol_size) diff --git a/sound/firewire/amdtp-stream.h b/sound/firewire/amdtp-stream.h index 7be2142..c1bc7fa 100644 --- a/sound/firewire/amdtp-stream.h +++ b/sound/firewire/amdtp-stream.h @@ -93,7 +93,7 @@ typedef unsigned int (*amdtp_stream_process_data_blocks_t)( unsigned int *syt); struct amdtp_stream { struct fw_unit *unit; - int flags; + enum cip_flags flags; enum amdtp_stream_direction direction; struct mutex mutex; @@ -137,7 +137,7 @@ struct amdtp_stream { }; int amdtp_stream_init(struct amdtp_stream *s, struct fw_unit *unit, - enum amdtp_stream_direction dir, int flags, + enum amdtp_stream_direction dir, enum cip_flags flags, unsigned int fmt, amdtp_stream_process_data_blocks_t process_data_blocks, unsigned int protocol_size); -- 2.9.3
